Title:
POWER SUPPLY CIRCUIT AND CHIP
Document Type and Number:
WIPO Patent Application WO/2024/036743
Kind Code:
A1
Abstract:
A power supply circuit and a chip using the power supply circuit. The power supply circuit comprises: a reference voltage generation circuit (1) used for generating a substrate reference voltage (Vref) of a positive temperature coefficient; a voltage generation circuit (2) used for boosting a substrate voltage (VBP) according to an enable signal (EN); and an enable signal generation circuit (3) connected to the reference voltage generation circuit (1) and the voltage generation circuit (2), and used for outputting the enable signal (EN) to the voltage generation circuit (2) when the substrate reference voltage (Vref) is greater than the product of the substrate voltage (VBP) and a preset coefficient. The substrate voltage of a transistor can be boosted when the temperature is increased, such that the power consumption of the chip is reduced.
