Abstract
A pulse generating unit receives a clock at a predetermined frequency, and generates a pulse signal which transits synchronously with the positive edge of the clock. A flip-flop acquires the pulse signal every time a positive edge occurs in an inverted clock output from the inverter. A logic gate multiplexes the pulse signal and the output of the flip-flop. A selector selects either the output of the logic gate or the pulse signal.
