Counter circuit using current source

摘要: An integrated counter circuit includes a charge storage capacitor having charging path connected in series with an interrupted current source which is rendered alternately conductive and nonconductive by the input signal pulses or cycles are to be counted circuit. The on applied one of regenerative threshold switch supplied reference potential establish switching level. When becomes sufficiently high enough rapidly discharges capacitor. To enhance sharpness point switch, attenuated at frequency used inputs switch.
