dc analysis of cmos OTA with SC-CMFB

cmos ota

how to perform dc analysis of OTA with SC-CMFB and how to verify the OTA+SCCMFB is stable. I heard it is inherently stable, is it true?. Thanks in advance.

as SC-CMFB includes clock which is function of time, in performing dc analysis how do we account for it. this is urgent, please respond. Thanks in advance.

I don't hnow whether the DC analysis could be done to the SC-CMFB circuit with clock.
Someone told me that Tran analysis could be used to check the circuit is stable or not. After the analysis is done, check the output CM voltage is the certain value you want or not to decide whether the circuit is stable or not.
I don't know this for sure, just a suggeation.

cmos dc analysis

Thanks for your reply BackerShu, i know that transient analysis works but the thing is i would like to see the dc transfer function, so in dc analysis if the clocked circuit isn't taken into considereation then how can the dc analysis be done?
