Dear All,
In switched capacitor circuits such as inverting/non-inverting amplifiers and multiply by 2 circuits, there is always a period of time during which the output and one of the input terminals are shorted ( like a buffer configuration). My understanding is that this is done in order to establish a proper common mode input voltage. However, in case of switched capacitor Active filter circuits, there usually is never a period of time during with such operation is done. May I know why this is so.
Thanks a lot in advance!!
Best Regards,
M.
