Abstract: A voltage regulation circuit mainly includes an oscillator and a regulation circuit. The oscillator is connected to a power supply circuit configured to supply power to a logic circuit, and a process corner type of the oscillator is the same as a process corner type of the logic circuit. The oscillator may generate a first clock signal based on an output voltage of the power supply circuit. The regulation circuit may control, based on the first clock signal, the power supply circuit to regulate the output voltage. For a logic circuit of an SS corner type, the output voltage of the power supply circuit may be increased, and for a logic circuit of an FF corner type, the output voltage of the power supply circuit may be decreased.
