Activity: The Switched Capacitor [Analog Devices Wiki]
Each switching cycle transfers a charge Δq from the input to the output at the switching frequency F. Recall that the charge q on a capacitor C with a voltage V between the plates is given by: q = CV Where V is the voltage across the capacitor. Therefore, when S 1 is closed while S 2 is open, the charge transferred from the input source to C is: q IN = C 1 …

Time Delay Circuit with Capacitors, Transistors & Resistors
The transient response time, or the time the capacitor takes to charge fully, is equal to 5 times this value. Since we''re using a 100μF capacitor and there is a resistance of 20K in the circuit, the time constant is .0001F x 20,000R = 2 seconds. Multiply that value by 5 and you have a capacitor charge time of 10 seconds.
