Abstract

A drive circuit with parallel drive architecture consists of a plurality of parallel drivers. Each driver includes a switch, a control voltage generating unit, and a drive unit. The control voltage generating unit connects to a voltage source through the switch, and generates a set of output voltages after having received a pair of differential signals. The drive unit receives the set of output voltages from the control voltage generating unit, and accordingly generates a first drive current at a first output terminal and a second drive current at a second output terminal. Wherein, the first terminal of the drive unit of each driver is connected to each other for generating a first output current, and the second terminal of the drive unit of each driver is connected to each other for generating a second output current. Based on user's demand, the invention controls the multi-level output current by using the switch to turn ON or OFF each driver through the parallel architecture. Also, the invention has advantages of non-increasing layout size and low power consumption.
