MUMBAI, India, July 31 -- Intellectual Property India has published a patent application (202047056647 A) filed by Shenzhen Goodix Technology Co. , Ltd. on December 28, 2020, for Boost Generation Circuit, Related Circuit And Chip, And Wearable Device.
Inventor includes Wang, Wen-Chi.
The application for the patent was published on July 24, 2026, under issue no. 30/2026.
Abstract: A boost generation circuit (10), a related circuit and chip, and a wearable device. The boost generation circuit (10) is provided with an output terminal (OUT), and the output terminal (OUT) supplies an output voltage (VOUT) and a load current (ILOAD). The boost generation circuit (10) comprises: a first charge pump (100) which supplies a first bias current (IB1); a second charge pump (102) which supplies the load current (ILOAD); an output voltage locking circuit (110) which draws the first bias current (IB1) from the first charge pump (100) to the output terminal (OUT), wherein the output voltage locking circuit (110) locks a first charge pump voltage (VPUMP1) of the first charge pump (100) by means of locking the first bias current (IB1), and further locks the output voltage (VOUT) on the basis of the locked first charge pump voltage (VPUMP1); and a load current generation circuit (120), which draws the load current (ILOAD) from the second charge pump (102) to the output terminal (OUT) on the basis of a second charge pump voltage (VPUMP2) of the second charge pump (102).
