Latest Patents

Liu's latest patents include a current detection circuit and an electronic device. The current detection circuit comprises a signal input terminal, a signal output terminal, a switch branch, a first current detection branch, and a second current detection branch. The switch branch is designed to block the current flowing from the signal output terminal to the signal input terminal when it is turned off. When the switch branch is conducting, the current flowing from the signal input terminal through the switch branch to the signal output terminal is the switch branch current, which consists of a first part that is linearly related to a first voltage difference and a second part that is exponentially related to the first voltage difference. The first voltage difference is defined as the voltage difference between the signal input terminal and the signal output terminal. The first current detection branch outputs a first detection current representing the first part, while the second current detection branch outputs a second detection current representing the second part.

Another notable patent is related to a high side current detection circuit, overcurrent protection circuit, calibration method, and electronic devices. This calibration method involves obtaining an offset error of the overcurrent protection circuit by changing its current limiting state. It also includes adjusting an offset compensation circuit to calibrate the offset error and adjusting a gain calibration circuit based on the current limiting state to calibrate a gain error of the overcurrent protection circuit. The overcurrent protection circuit consists of multiple transistors, an operational amplifier, a gain calibration circuit, an offset compensation circuit, and a driving circuit, which generates a gate drive signal applied to the first and third transistors.
