Title:
POWER SUPPLY CIRCUIT AND CHIP
Document Type and Number:
WIPO Patent Application WO/2024/036744
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 negative temperature coefficient; a voltage generation circuit (2), used for reducing a substrate voltage (VBN) according to an enable signal (EN); and an enable signal (EN) 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 less than a conversion voltage proportional to the substrate voltage (VBN). The substrate voltage of a transistor can be reduced when the temperature rises, and then power consumption of the chip is reduced.
