Patent number: 11940828Abstract: A voltage tracking circuit is provided. The voltage tracking circuit includes first and second P-type transistors and a control circuit. The drain of the first P-type transistor is coupled to a first voltage terminal. The gate and the drain of the second P-type transistor are respectively coupled to the first voltage terminal and a second voltage terminal. The control circuit is coupled to the first and second voltage terminals and generates a control voltage according to the first voltage and the second voltage. The sources of the first and second P-type transistors are coupled to an output terminal of the voltage tracking circuit, and the output voltage is generated at the output terminal. In response to the second voltage being higher than the first voltage, the control circuit generates the control signal to turn off the first P-type transistor.Type: GrantFiled: August 17, 2022Date of Patent: March 26, 2024Assignee: VANGUARD INTERNATIONAL SEMICONDUCTOR CORPORATIONInventors: Shao-Chang Huang, Yeh-Ning Jou, Ching-Ho Li, Kai-Chieh Hsu, Chun-Chih Chen, Chien-Wei Wang, Gong-Kai Lin, Li-Fan Chen
