Capacitor Charge Pump with Counter

Includes a counter that helps keep track of how many cycles it takes to fully charge the capacitor. The counter will stop and hold its value once the voltage across the capacitor reaches the voltage threshold set by the D.C. source on the non-inverting input of the OP AMP (the orange trace). You can then use this counter value to calculate how long it will take in real time to fully charge this capacitor with such circuit at the desired voltage level simply by multiplying the counter value by the period of the signal that drives the circuit. Counts all the way up to 9,999! Hopefully it won’t need to go that high though 😂😂
