Title
(EN) RELAXATION OSCILLATOR CIRCUIT FOR LOW FREQUENCY AND LOW POWER DISSIPATION
(FR) CIRCUIT OSCILLATEUR DE RELAXATION POUR UNE DISSIPATION DE BASSE FRÉQUENCE ET DE FAIBLE PUISSANCE
Abstract
(EN)
A relaxation oscillator circuit includes a current mirror configured to receive the input current from the and generate a plurality of starved currents, a Schmitt trigger configured to be current starved by a first starved current of the plurality of starved currents and a plurality of inverters configured to receive a Schmitt trigger output signal and generate an output clock signal, the inverters including a plurality of current starved inverters that are current starved by a second starved current of the plurality of starved currents, the plurality of current starved inverters receiving the Schmitt trigger output signal and generating a first inverter output signal, upon which an output clock signal is based. The relaxation includes a capacitor configured to charge or discharge in response to the output clock signal and a switching module configured to provide current from the current source based on the output clock signal.
