What happens if a capacitor is connected together in parallel?
When capacitors are connected together in parallel the total or equivalent capacitance, CT in the circuit is equal to the sum of all the individual capacitors added together. This is because the top plate of capacitor, C1 is connected to the top plate of C2 which is connected to the top plate of C3 and so on.
What is total capacitance of a parallel circuit?
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.

Can a switched capacitor circuit be used in a feedback loop?
One must be careful when using switched capacitor circuits in a feedback loop because of the excess phase delay. Transresistance circuits are two-port networks where the voltage across one port controls the current flowing between the ports. Typically, one of the ports is at zero potential (virtual ground).
