Razavi Electronics2 Lec15: High-Gain Differential Pairs, Intro. to Diff. Pair with Active Load

[rahulchatterjee]

Arguably the greatest teacher of electronics

[rahultheytv]

Thank you sir, ,, its very rare to find people sharing information with caring and no cost minds

Thank you sir, I understand what’s the potential means from this lecturer.

[deepdivdivdeep]

Thank you very much for the precious teaching from sir.

At 33:02, if you cant see the green writing, make a snapshot, put it in paint and reverse the Colors, so you can see it easy.

[vigneshrshankar]

It has a name.. If you don't like the name, don't worry about it ! :D

[mnada]

Waiting eagerly for circuit theory I & II and the rest of the series.

[vimalkantpandey]

Thank you very much. When you are going to upload other videos of this series like Lecture 14 and others

[brucemuller]

In differential pair with active load, when ID1 increases, ID3 increases, so ID4 increases due to mirroring...but ID1+ID2 = Iss which is constant...and ID2=ID4 so by this logic ID4 should decrease when ID1 increases.
Does it mean that M4 is in triode region?

[sandeepmaurya]

Sir please do not use green color, it is not clear though.

[vaisnavashok]

Why are the videos having an abrupt ending?

[oakspines]

We use active load instead of passive resistor.

[saisumanthnatva]

At 7:53, ideal current source should be replaced by a resistance (internal resistance of a mosfet, let's say ro3). So, gain will be -gm(ro1 ll ro3). Isn't it?

[varaprasadgrandhi]

Sir what is the difference between the regisitive load and current load. Because they are having same representation in mos diagrams.

[kunalvatwani]

So basically m1 wants id1 to increase which increases id2 so Vout increases
And M2 wants to decrease id2 so that Vout increases.
id2 both increases and decreases and in both cases increases
Something seems wrong

[amitkumar-shlk]

Sir please dont use light green colour for writing as it is not visible . istead u can use dark green colour

[mhmd_rjb]

47:34 P can't be ac ground anymore

[shikharsrivastava]

42:24 please xplain, i didnt understand the 2 case
