Abstract
A voltage controlled circuit includes a tracking circuit, an operational amplifier, a transistor, a feedback circuit and a sample and hold circuit. The tracking circuit generates an updated enabling voltage according to an enabling voltage, a sample enabling voltage and a sample reference voltage. The operational amplifier includes a first input terminal used to receive an input voltage, a second input terminal used to receive a feedback voltage, and an output terminal used to output a control voltage. The transistor includes a control terminal used to receive the control voltage, a first terminal used to receive a reference voltage, and a second terminal used to output a regulated voltage. The feedback circuit generates the feedback voltage according to the regulated voltage. The sample and hold circuit is used to sample the input voltage to generate the sample enabling voltage, and sample the feedback voltage to generate the sample reference voltage.
