hi all , I have designed a folded cascode ota with both ideal and switched capacitor cmfb. With ideal cmfb open loop gain is 67dB but when used with sc cmfb the gain decreases to 33dB . What is the reason for this ? in sc cmfb non-switched capacitor value is 200fF and switched capacitor value is 100fF. clock frequency is 10.24M
