At time 6:11 in the video, I thought the equation should be Vx=[ i_x - g_m2 * (-i_x * r_o1 ) ]* r_o2 + i_x * r_o1 it seems to me that in your top most equation at timestamp 6:11 you have a plus sign instead of a minus sign before g_m2. Is this an error?

When performing small signal analysis, shouldnt Vgs2 = 0 so Id2 is zero (because Vgs2 is a DC voltage source)?

If ac source is at the bottom transistor, what will happen if you keep Vgs2=0 and do the small-signal analysis?
@ALLABOUTELECTRONICS

I think you are talking about small-signal analysis right ?? If vgs2 = 0 then the second MOSFET can be replaced by its output impedance. Ro2 and Ro1 will be in parallel.

Why we have to ground the output voltage to find eqivalent Gm?
@ALLABOUTELECTRONICS
3 жыл бұрын
Just consider the entire circuit as a two-port network. The transconductance Gm is the ratio of output current to the input voltage. If you recall the two-port network lectures then it is Y-parameter. I2/V1 when V2 = 0. That's why while finding Gm, output was grounded. I hope, it will clear your doubt.

Shouldn't there be minus sign in the intrinsic gain of the cascode amplifier ?
@ALLABOUTELECTRONICS
3 жыл бұрын
Yes, there will be a minus sign. But in the video if you observe, then only magnitude of intrinsic gain |Ao| is represented. That's why there is no negative sign.

Yeah but how does it work in a few sentences without all the math?
