Abstract :
This paper presents a model of the frequency sensitivity to the control voltage (Kvco) of a ring oscillator. The proposed model is devoted to the PMOS symmetric load Ring oscillator. An example considering a 2.5 V CMOS 65 nm is presented where the accuracy of the results are presented and compared to those obtained using ELDO simulator.
