ABSTRACT:
An improved oscillator circuit utilizes an inverter which includes a pair of series connected MOS-FETs of differing conductivity types. A switching circuit is operable to supply the gate bias voltages from one of two separate sources, one of which is used during periods of start-up or unstable oscillation to decrease start-up time, and the other of which is used during periods of stable oscillation to decrease current consumption.
