Introductory Chapter

Chapter 1. Basic Sinusoidal Oscillators and Waveform Generators Using IC Building Blocks
Abstract
This chapter discusses the basic principle of generating sinusoidal oscillators, reviews the classical sinusoidal oscillators and nonsinusoidal waveform generators, enumerates a number of other sinusoidal oscillator topologies, and outlines some basic methods of oscillator analysis and synthesis.

Chapter 2. Single-Element-Controlled and Other Varieties of Op-Amp Sinusoidal Oscillators
Abstract
This chapter presents a comprehensive treatment on the evolution of single-element-controlled oscillators (SECOs) in general and single-resistance-controlled oscillators (SRCOs) in particular. The discussion includes a wide variety of op-amp-based oscillators such as single-op-amp-based SRCOs, grounded-capacitor (GC) SRCOs, and unity gain amplifier-based SRCOs. Also included are oscillators with linear tuning laws, varieties of active-R oscillators, and op-amp-based voltage-controlled oscillators (VCOs).

Chapter 3. Electronically Controllable OTA-C and Gm-C Sinusoidal Oscillators
Abstract
OTA-C oscillators and Gm-C oscillators are attractive due to a number of advantageous features provided by them, namely, electronically controllable frequency of oscillation as well as condition of oscillation and suitability for integrated circuit implementation in both bipolar and CMOS technologies since OTAs do not require any resistors and are implementable exclusively using transistors only. Furthermore, in circuits containing OTAs or transconductors (Gm), all functions can be invariably performed without requiring any passive resistors (of course, wherever needed, resistor(s) can always be simulated by OTA(s)/transconductor(s)). In this chapter, we present significant developments taken place in the area of realization of electronically controllable sinusoidal oscillators using OTA-C and Gm-C circuits.

Chapter 4. Sinusoidal Oscillators Using Current Conveyors
Abstract
This chapter discusses the evolution of sinusoidal oscillators using the new active building blocks known as Current Conveyors by Sedra and Smith in 1968–1970. Although fixed frequency oscillators as well as variable frequency oscillators both have been discussed, a major emphasis has been on the so-called single-element-controlled oscillators. A large variety of CC-based sinusoidal oscillators have been evolved so far which include both single CC-based as well as two or more CC-based oscillators, including quadrature and multiphase oscillators. Oscillators employing all grounded passive elements as well as those providing explicit current output have also been discussed.
Raj Senani, D. R. Bhaskar, V. K. Singh, R. K. Sharma
Chapter 5. Realization of Sinusoidal Oscillators Using Current Feedback Op-Amps
Abstract
After briefly outlining the significant advantages offered by CFOA-based sinusoidal oscillators, a variety of prominent single-resistance-controlled oscillators (SRCO) have been described which include single CFOA-based SRCOs, two-CFOA-two-grounded-capacitor-based SRCOs, quadrature SRCOs, active-R SRCOs, SRCOs with explicit current output, and fully-uncoupled SRCOs. Also included are a variety of voltage-controlled oscillators (VCO) using CFOAs, employing FET-based VCOs as well as analog multiplier (AM)-based VCOs. Various characteristic features and advantages of all the discussed topologies have been highlighted and a number of ideas for further research have been pointed out.

Chapter 6. Sinusoidal Oscillator Realizations Using Modern Electronic Circuit Building Blocks
Abstract
A variety of SRCOs realized with numerous variants of CCs introduced in the literature as well as using a number of other new building blocks have been discussed. Our endeavor here has been on including only some representative circuit configurations (from amongst a large number of oscillator circuits reported in literature) which possess some specific attractive features of practical interest; interested readers can explore other options from the list of references provided at the end of the chapter.

Chapter 7. Switched-Capacitor, Switched-Current, and MOSFET-C Sinusoidal Oscillators
Abstract
This chapter presents some prominent sinusoidal oscillator configurations from the various switched-capacitor, switched-current, and MOSFET-C sinusoidal oscillators evolved so far. Whereas the first two classes of oscillators are essentially discrete time systems, the third one is, by contrast, a continuous time system. However, all the three types of oscillators have the common features of (a) electronic tunability of the oscillation frequency and (b) the suitability of the circuits for integrated circuit implementation in CMOS technology and have, therefore, attracted considerable attention in technical literature.
Raj Senani, D. R. Bhaskar, V. K. Singh, R. K. Sharma
Chapter 8. Current-Controlled Sinusoidal Oscillators Using Current-Controllable Building Blocks
Abstract
In many applications, one requires an oscillator or waveform generator whose frequency can be varied through either a single external voltage or an external current. In this chapter, a variety of such electronically controllable oscillators would be introduced using modern current-controllable building blocks. Electronically controllable quadrature and multiphase oscillators are also included.

Chapter 9. Bipolar and CMOS Translinear, Log-Domain, and Square-Root Domain Sinusoidal Oscillators
Abstract
Translinear, log-domain, and square-root domain analog signal processing circuits potentially offer high-frequency operation and extended dynamic range at low power supply voltages and have, therefore, been widely investigated in literature due to being also very promising for implementation in IC technology because of employing only transistors (BJTs/MOSFETs) and very low-valued capacitors (having values of the order of a few pF) and providing electronic tunability of the parameters of the realized functional circuits. In this chapter, we discuss some significant contributions made in the realization of fully integratable sinusoidal oscillators evolved during the past two decades using translinear, log-domain, and square-root domain techniques and circuits.

Chapter 10. Generation of Equivalent Oscillators Using Various Network Transformations
Abstract
This chapter discusses a number of transformations which have been proposed by various researchers from time to time to generate several equivalent configurations of a given sinusoidal oscillator.
Raj Senani, D. R. Bhaskar, V. K. Singh, R. K. Sharma
Chapter 11. Various Performance Measures, Figures of Merit, and Amplitude Stabilization/Control of Oscillators
Abstract
In this chapter, the various performance criteria and figures of merit related to oscillators are highlighted and some prominent circuits and techniques of amplitude stabilization/control of oscillators are elaborated. Amplitude stabilization/control of current-mode oscillators is also considered.

Chapter 12. Non-sinusoidal Waveform Generators and Multivibrators Using OTAs
Abstract
This chapter presents various waveform generators using OTAs. This includes a variety of Schmitt triggers, astable multivibrators, monostable multivibrators, and pulse-width-modulators. Most of the circuits can be practically implemented using the off-the-shelf IC OTAs. The advantages and limitations of the various circuits are highlighted and a number of promising ideas for further work are also pointed out.
Raj Senani, D. R. Bhaskar, V. K. Singh, R. K. Sharma
Chapter 13. Waveform Generators Using Current Conveyors and CFOAs
Abstract
Whereas a large amount of work has been done on the synthesis of Sinusoidal oscillators using Current Conveyors and CFOAs, comparatively very little has been done on the realization of relaxation oscillators and non-sinusoidal wave form generators using the mentioned building blocks. The intention of this chapter is, therefore, to present the prominent work done in this direction till date.

Chapter 14. Nonsinusoidal Waveform Generators/Relaxation Oscillators Using Other Building Blocks
Abstract
In this chapter, we present various multivibrator circuits and nonsinusoidal waveform generators realized with active building blocks of relatively more recent origin. In particular, we present circuit configurations for the functions mentioned above using OTRAs, current differencing buffered amplifiers, current conveyor transconductance amplifiers, and current differencing transconductance amplifiers.
