Obtaining " gm " value of a mos in cadence virtuoso

In order to obtain gm value of a mos for hand calculations of capacitance etc,
1) Perform dc analysis ( simple dc analysis).
2) Use " direct plot " if the conventional method of dc analysis takes too much time (as it did in my case).
3) Analog simulation envt->results
4) Select the option that gives you transistor parameters

4) Right click on gm. Select table and you will obtain the gm of the desired mosfet :)

Design of a 2 stage op amp

DESIGN CONSTRAINTS:
1)SR = 10 V/usec
2)Av = 5000 V/V
3)GB = 5 MHz
4)CL = 100 fF
5)Pdiss < 0.3 mWatt
6)ICMR+ = 1.5 Volt
7)ICMR- = 0.2 Volt
Design consideration:
We consider that
1)10uA current flows through 1st stage
2)20uA current flows through the next stage
3)A cascoded current mirror it used for realizing the current source( vary its W/L to get 20uA and 10uA currents resp).
TECHNOLOGY USED: 180nm technology corresponding AC analysis gives:
This is the Mag-Phase plot for (0-10^12)Hz frequency range.

Problems Encountered:
1) Regarding phase plot:
Between (10^8- 10^9),in the magnitude curve, we have a - 40dB slope(due to presence of poles) .There after we have a zero. So theoretically there should be a positive slope for the phase plot (due to the presence of zero), though no such thing can be observed from the simulation result.
2) Regarding frequency compensation:
Variation in R and Cc is not giving much difference in the frequency response (phase margin).
