I am designing fully folded cascode OTA with PMOS input and CMFB. Whenever I run Cadence, the simulation result is way different from my hand calculation result and I am having hard time to make my OTA work on operating point and I really don't know what to do..
I would very much appreciate if you could give me any advice or send me some papers or good sources I can refer to. (step by step tutorial)
Best Regards

TSMC 0.18 micron technology
DC gain:60dB
Gain bandwidth product:500MHz
Phase Margin: 60
Output swing: 1v P-P
Output Load: 2pF
Slew rate: 20v/usec
fully differential..

For this design, Which Vdd should I use
1.8V or 3.3V?
And What L do I need to use? 0.18um, 0.36um....0.90um........or 1.8um???????????
