Power consumption in an oscillator formed of a chain of two inverters in series, with resistive feedback from the output of the first inverter to its input, and capacitive feedback from the output of the second inverter to the input of the first inverter is lowered by reducing the supply voltage to the two inverters and reducing the voltage swing at the input to the first inverter. The supply voltage is reduced by adding one or more diodes, or other voltage reducing elements or means for reducing the voltage, between the power and ground rails of the power source and the power and ground inputs of the two inverters, and the voltage swing is reduced by selecting the feedback capacitor.
