Abstract :
This paper presents a new technique to improve the frequency stability and amplitude stability with respect to temperature of ring oscillator using CMOS technology at 500nm technology using 3 volts supply voltage with 100fF load capacitance. There are several proposed architecture for the improvement in frequency stability and amplitude stability of sinusoidal output waveform. Proposed structure 1 based on addition of feed-forward path increases the frequency stability and amplitude stability whereas the proposed structure 2 based on the addition of feedback path increases the frequency stability and amplitude stability with respect to temperature.
