Abstract
A power ground noise reduction system includes a bandgap circuit and a noise reduction circuit. The bandgap circuit includes an input terminal for receiving a working voltage, and an output terminal for outputting a bandgap reference voltage. The noise reduction circuit includes a first input terminal coupled to the output terminal of the bandgap circuit for receiving the bandgap reference voltage, a second input terminal for receiving the working voltage, a ground terminal coupled to a low voltage terminal, a first current source for receiving the working voltage received by the second input terminal and generating a first current, and a second current source for generating a second current to the low voltage terminal through the ground terminal.
