please can someone explain to me why there would be charge/ current leakage in switched capacitor circuits at very low frequencies?
I read it somewhere but didn't get any explanation.
Thanks.

You can also have trouble with the input transistors in the OTA used with the switched capacitor. This problem gets worse and worse in deep submicron technologies and puts a lower limit on the frequency of operation of many practical circuits, such as Pipelined ADCs. Also, when you make the caps small to go fast, you make the problem worse.
