WIPO Patent Application WO/2021/212288

Kind Code:

A1

Abstract:

Provided are a voltage regulation circuit and method, an operation system, and an integrated module and circuit. The voltage regulation circuit (31) mainly comprises: an oscillator (311) and a regulation and control circuit (312), wherein the oscillator (311) is connected to a power source circuit (32) for supplying power to a logic circuit (33), and the process corner type of the oscillator (311) is the same as the process corner type of the logic circuit (33); and the oscillator (311) can generate a first clock signal (CLK1) according to an output voltage of the power source circuit (32), and the regulation and control circuit (312) can control, according to the first clock signal (CLK1), the power source circuit (32) to regulate the output voltage. For a logic circuit of an SS corner, the output voltage of the power source circuit (32) can be increased, and for a logic circuit of an FF corner, the output voltage of the power source circuit (32) can be decreased, thereby facilitating the optimization of timing margins of the logic circuit of the SS corner and the logic circuit of the FF corner.
