Показать описание
In this video we'll learn about design and analysis of differential amplifier with active load using potential division method ( PDM ) and find out Gain Av using ac analysis, and then perform transient analysis. Also we'll find out the proper sizing of W and L and slew rate.

How to find out the PM of the op-amp? please find it

You always get a gain in the 35-40 dBs. How PDM make sure that the gain is always higher than 30dBs. What if you want more gain out of it? What if you want to modify the Phase Margin. What will you do if you are not free to vary the width of the device? How the theory of op-amp correlates with PDM method. Please explain if possible, as all these questions create more confusion than solving the issue.
