Relaxation oscillator output voltage linearity

Abstract

Abstrucf -This paper analyses the output voltage nonlinearity of current switching relaxntion oscillator. An analytical modeltaking into account the current sources finite output resistanceis developed, in order (1) to get more precise design equation for transistor lengtfi and (2) to evaluate the oscillation amplitude influence on the oscillation frequency. The results obtained for an oscillntor realized using B standard 0.6 pn CMOS process were checked by SPICE simulation.Inder term -relaxation oscillator, output voltage linearity, oscillation frequency.
