Patent ID: 11656643

Abstract:
A circuit for converting a first voltage to a second voltage in a communication system is disclosed. The circuit includes a pass transistor including a first terminal, a second terminal and a gate, wherein the first terminal is coupled with the first voltage. The circuit is also includes an error amplifier. The error amplifier includes a first input that is coupled with a constant reference voltage and a second input that is coupled with a first switch that is coupled with an output port. A second switch is included and is coupled between the first voltage and an output of the error amplifier. The output of the error amplifier is coupled with the gate of the pass transistor. A third switch is included and is coupled between ground and the output of the error amplifier. The second switch is configured to be driven by a first one shot pulse generated from an input signal of the communication system and the third switch is configured to be driven by a second one shot pulse generated from the input signal.
