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.

A low-power consumption, high-speed electronic switching system has a pair of complementary switching means connected between opposite polarity terminals of the voltage source and an output terminal. The pair of switches provides a variable impedance for applying one or the other of the polarities and said output terminal. To speed an appearance of that polarity, an inverter is coupled between an input and an output terminal via a differentiating capacitor. The differentiated inverter output speeds the appearance of the switched output signal during the interval before the complementary input becomes effective thereat.
