Abstract
A clock driver circuit, including: an input stage, a double-ended to single-ended conversion stage and a driver output stage connected in sequence. The input stage includes two mutually loaded differential amplifiers and a common mode negative feedback loop. The differential amplifiers are connected to a differential clock signal for amplification to generate a common mode voltage. The common mode feedback circuit is connected to an output end of the differential amplifiers to stabilize the output amplitude of the common mode voltage. The double-ended to single-ended conversion stage converts a differential sine clock signal output by the double-ended common mode voltage into a single-ended square wave clock signal. The driver output stage includes a multi-stage cascaded push-pull phase inverter to improve the drive capability of the square wave clock signal.
