Dear All,
I need to design a simple single-ended differential input pair OTA for gm-C filter.
Here the Gm-block should operate in open-loop configuration. So if there is no negative dc feedback how can I ensure the output common-mode level. To provide only DC-feedback, I need to use large resistor and large capacitor which is not feasible for on-chip integration. Please suggest me some on-chip biasing technique for such cases.
regards
Sam
