Title:
POWER SUPPLY CIRCUIT AND CHIP
Document Type and Number:
WIPO Patent Application WO/2024/036742
Kind Code:
A1
Abstract:
A power supply circuit (100) and a chip applying the power supply circuit (100). The power supply circuit (100) comprises: a constant current generation module (1), which is used for generating a first current (I1) with a positive temperature coefficient and a second current (I2) with a negative temperature coefficient, and generating a constant current (I) according to the first current (I1) and the second current (I2); and a voltage generation module (2) which comprises a transistor, is coupled to the constant current generation module (1) and is used for generating a temperature-related voltage (V) according to the constant current (I) and transistor characteristics. The power supply circuit (100) can generate a voltage (V) related to the transistor characteristics and the temperature. The circuit structure is simplified, and the chip volume is reduced.
