How can I make M6 to operate in saturation region? (Two stage amp case)
And How do I determine D-S voltage of M6?
Figure below shows a case in which the voltage of node 1 is 87mV
so it does not operate in the saturation region.
I want to know the difference between gm/id and Vov method when designing amplifier.
And why use the gm/id method.
As far as I know, there are three aspects.
1. Available for low power designs.
2. Gm, id, L, and w of input Mosfet pair can be found more systematically at specified power and...
I meant single stage CS amplifier.
Does the intrinsic gain "gmro" continue to goes up if I keep increasing W/L in a single-stage CS amplifier? Is there any limit?
What happens when I huge W/L mosfet in the single stage amp?
I think if I keep raising w/l, the total gain will be increased and the GBW will be reduced due to parasitic Cgs. Am i right? Also, I want to know what changes will occur if I actually use a huge w/l except for the size problem...
