A New Solution to Analysis of CMOS Ring Oscillators
Research Paper
Research Paper
New equations are proposed for frequency and amplitude of a ring oscillator.
The method is general enough to be used for all types of delay stages. Using exact largesignal
circuit analysis, closed form equations for estimating the frequency and amplitude of
a high frequency ring oscillator are derived as an example. The method takes into account
the effect of various parasitic capacitors to have better accuracy. Based on the loop gain of
the ring, the transistors may only be in saturation or experience cutoff and triode regions.
The analysis considers all of the above mentioned scenarios respectively and gives distinct
equations. The validity of the resulted equations is verified through simulations using
TSMC 0.18 µm CMOS process. Simulation results show the better accuracy of the
proposed method compared with others.
