Title:
DRIVE CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/269953
Kind Code:
A1
Abstract:
The present invention improves signal quality in a drive circuit having a driver. This drive circuit comprises a driver, an amplitude adjusting unit, and a common voltage adjusting unit. In the drive circuit, the driver outputs a differential signal. The amplitude adjusting unit generates, from one of a pair of voltages, the other of the pair of voltages, and supplies the other voltage to one of a power supply terminal and a ground terminal of the driver. The common voltage adjusting unit generates, from an intermediate voltage of the pair of voltages, one of the pair of voltages, and supplies the one voltage to the other of the power supply terminal and the ground terminal.
