switch cap integrator
i have designed a differential switched capacitor integrator. but the problem is at the output i am not getting the full step what i required.
The ota i have used is the telescopic ota having a gain of 63db, ugb of 1.3GHz and
2 volts pek-peak output swing for a supply voltage of 3.3volts in 0.18u technology.
i applied differential input of 250mV at input but at output step size i got is 246mV
only for the capacitors ratio of 1.
can anyone help me what may be the problem
