A device and method for generating a symmetrical clock signal. The device comprises a signal generator, buffer and differential amplifier. The signal generator generates a periodic wave signal. The buffer receives the periodic wave signal and provides a square wave clock signal. The differential amplifier receives the clock signal and a reference voltage signal and provides an error signal to the buffer.
