Abstract
The purpose of this paper is to show that exists a close relationship between some CCII+ based sinusoidal oscillators and the RC active second order oscillators with a single VCVS. These structures with CCII+ may be derived from the classic Wien-bridge oscillator, and four of them exhibit practical interest. They are canonical, the oscillation condition can be adjusted by a single resistor, and furthermore, they may be designed with the same procedure as their voltage amplifier counterparts. Experimental and simulation results supporting the theoretical analysis are given.
