Abstract:
An amplifier circuit includes: a Schmidt trigger having an input electrically coupled to an input of the amplifier circuit, a switching network electrically coupled to an output of the Schmidt trigger, an inductor electrically coupled to the switching network, a first resistor electrically coupled to the inductor, a capacitor electrically coupled to the first resistor, a first feedback circuit that provides a first feedback signal to the input of the Schmidt trigger based on a voltage at a first node electrically coupled to the first resistor and to the capacitor, a second resistor electrically coupled to the output of the amplifier circuit, a third resistor electrically coupled to the second resistor, and a second feedback circuit that provides a second feedback signal to the input of the Schmidt trigger based on a voltage at a second node electrically coupled to the second resistor and to the third resistor.
