ABSTRACT:
A low power, single pin CMOS oscillator has been provided which exhibits good frequency stability with voltage supply variations. The oscillator uses a capacitor which is connected to the inputs of two inverters. One inverter is used to drive a P-channel transistor and the other inverter is used to drive an N-channel transistor. Both P-channel and N-channel transistors are connected in series and provide an output from a junction formed between the two transistors. A latch is connected to the junction formed between the two transistors and the output of the latch is coupled to the capacitor to charge and discharge it.
