A voltage-controlled ring oscillator with an RC delay as an additional delay to vary the oscillation frequency is proposed. The use of MOS resistors provides a wide range tuning ability from 40 Hz to 366 MHz. The proposed circuit also enables implementation of a low frequency voltage-controlled ring oscillator with relatively smaller devices than the conventional one.
