Figure 9: Transient analysis of integer order CO with (a) L=100p and (b) L=1p.
After the transient analysis, AC analysis has been performed. The AC analysis involves computing the AC complex node voltages as a function of frequency using an independent voltage or current source as the driving signal. For this a dc voltage source (Vdc=1V) is employed to provide excitation to the oscillator. This gives the small signal analysis results with variation of magnitude as frequency varies.
