Abstract

This paper presents a new low voltage low cost quadrature oscillator, which consists of two LC negative oscillators based on active inductor. In this quadrature oscillator, the back-gates of the core transistors are used as coupling terminals to provide the quadrature outputs. The proposed floating active inductor has a two layer transistor structure. The quadrature oscillator has been implemented with the chart 0.18 \(\upmu \)m CMOS technology. At the supply voltage of 1.2 V, the total power consumption is 16 mW. The phase noise at 1 MHz frequency offset is \(-\)111.8 dBc/Hz at the oscillation frequency of 3.946 Hz.
