ABSTRACT:
An apparatus includes a first trigger, a second trigger, a pulse generator, and a control unit. The first trigger generates a first trigger signal and a first level signal; the second trigger generates a second trigger signal and a second level signal; the pulse generator generates a digital output signal according to the first and the second level signals; and the control unit outputs the first and the second control voltages according to the digital input signal and the digital output signal.
