Analog capacitance meter ( CD4013 )

Published:2012/8/17 1:43:00 Author:Ecco | Keyword: Analog capacitance meter | From:SeekIC

With a dual D flip-flop CD4013, a trigger and the measured capacitor form a monostable multivibrator toproduce the output pulse, the output pulse width,current average value and of the capacitance of the measuredcapacitor areproportional. The other flip-flop can form a multivibrator to generate the trigger pulse. An IC can form a simple capacitance meter. The measuring range : l00pF ~ lμF.
