DC, AC Analysis of OPAMP in Cadence and Power consumption of any circuit.

This tutorial I am showing how to do the ac, dc analysis of an operational amplifier and also how to measure the power consumption of OPAMP or any other circuit in general:
1. in DC analysis, I try to show what is dc analysis, how to do it and how to display the dc operating points, node voltages etc.
2 In AC analysis, I try to show how to do see the small signal performance of amplifier and calculate different parameters like GAIN, BANDWIDTH, PAHSE etc.
3. POWER CONSUMPTION, I showed how to measure power consumption in cadence.
