Abstract :
Designs for ring oscillators that provide a 2:1 range of voltage-controllable frequency are compared. Simulated results are given for a ring oscillator intended for a 1 ¿m NMOS monolithic IC implementation. The circuit displays a variable frequency from 1.5 GHz to 2.5 GHz, and requires no off-chip tuning elements.
