hello everyone
i have designed the analog schematic of a operational transconductance amplifier(OTA) circuit in CADENCE .

now i want to measure the following parameters of the designed circuit:-
1) Dc gain
2) unity gain bandwidth
3) phase margin
4) power consumption
5) settling time
6) output swing
7) input referred noise

Can anyony please tell the procedure to measure these properties, or, provide me with test circuit to measure the above mentioned parameters.

1)~3) AC simulation or STB analysis
4) DC sweep
5) transient
6) DC sweep
7) noise analysis

I am afraid, the above reply will not help to much. Perhaps the same applies to my answer.
I think, there is no specific "procedure" to simulate the mentioned parametrs.
My recommendation is simply to read/recognize and then to apply the definitions of the various parameters.
The only critical point is perhaps the dc gain because you have to find and compensate the offset voltage before or to simulate the dc transfer curve. However, in partucular this point was discussed in the forum recently.

I just listed command for cadence ADE environment.
I encourage him to try the menu just as learning various software.

The spice should have LM13600 ... its a National Semiconductors device listed in the library... so you might wanna search it by LM 13600_NE like that
