Abstract
A pulse duty cycle automatic correction device has a pulse width detector for detecting the high, low level pulse widths of the input cycle pulse so as to generate high, low level signals; a comparator encoder for comparing the high, low level signals, calculating out a correction delay time, and generating a correction delay signal and an output selection signal; a delay circuit for generating a delay cycle pulse; a compensation circuit for compensating the input cycle pulse so as to generate an input compensation pulse; a logic circuit for generating two cycle pulses according to the delay cycle pulse and the input compensation pulse; and a multiplexer for receiving the two cycle pulses and the input cycle pulse, and generating the output cycle pulse with duty cycle of 50% according to the output selection signal.
