ABSTRACT:
The output of the first CMOS inverter, connected as an oscillator, is applied to the inputs of second and third CMOS inverters that have logic threshold voltages higher and lower than the logic threshold voltage of the first inverter. The outputs of the second and third CMOS inverters are connected to an output circuit via a logic output circuit. The output of the logic output circuit is shorted by an output control circuit, under the control of the outputs of the second and third CMOS inverters, when the output of the oscillator is between the logic threshold voltages of the second and third inverters.
