VARIABLE DELAY CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a delay circuit capable of adjusting delay times with respect to the rise and fall of an input signal after it is manufactured. SOLUTION: This circuit includes plural switchable resistance elements, which are connected in parallel, consists of a delay element which delays an input signal via plural resistance elements and gets an output signal and a delay time controlling part 10 which selectively sends a switching control signal to plural resistance elements and controls delay time of the rise or fall of the input signal respectively by controlling ON/OFF of the resistance elements with a control signal from the part 10 and changing the resistance value.
