Patent ID: 11874682
Assignee: INFINEON TECHNOLOGIES AG
Field: Control (Instruments)
Classification: CPC G  H | IPC G  H

Claim 14:
15. A method of operating a circuit, the method comprising:
sending a first input signal to a first load circuit coupled between a first node and a reference voltage node;
sending a second input signal to a second load circuit coupled between the first node and the reference voltage node; and
powering the first load circuit and the second load circuit by providing a voltage to the first node using a voltage regulator, wherein the voltage regulator comprises:
a first transistor coupled between a voltage supply node and the first node;
a second transistor and a second switch coupled in series between the voltage supply node and the first node; and
an amplifier, wherein a first input terminal of the amplifier is coupled to a reference input voltage, a second input terminal of the amplifier is coupled to the first node through a feedback network, and an output terminal of the amplifier is coupled to a first gate terminal of the first transistor and a second gate terminal of the second transistor;

wherein powering the first load circuit and the second load circuit comprises:
flowing a first current through the first transistor into the first node; and
opening and closing the second switch alternately during normal operation of the circuit to flow a second current through the second transistor into the first node, wherein the second switch is configured to be closed by a control signal for a period of time when a falling edge or a rising edge is detected in the second input signal.
