Hi sir.All the videos that you have uploaded till now are fantastic and marvelous .It is very good initiative to help the people who are willing to learn analog basics.And also the way you are explaining the things from your experience is excellent.It would be much better if you diversify the topics into ADC,DAC,mixed signal and RF design also
thanks for great video again. in next video could you try to tell what is sigma value in BGR which is used commonly in industry? and how do we control it?
@@analogsnippets Thanks for the reply. I really like these videos. Especially because you talk about concepts and circuits as someone who has built intuition in industry. The standard textbooks are good but seeing how stuff is actually implemented in industry is great. For example, this BGR architecture when a chip is powered on. I like how you explained the schematic and why certain design choices were made. Keep up the good work! I hope there are more such videos in the future.
Dear Sir-Nice lecture. Could you please elaborate on the self-bias you did for the tail current of the opamp? Effectively that's another positive feedback, which we often ended up seeing the problem. Best Regards,Raj.
Which feedback are you referring to in resistor biasing? Essentially any current into amplifier forces current into diode branches and this causes start up.
Hello, Thanks for the informative tutorials. I would like to ask for some clarifications about the start up with R-as a current source and no additional circuitry. Please refer: ruclips.net/video/783Itlm-pUs/видео.htmlsi=Tqve3zdylIq7CtUR&t=627 Even if the Amplifier comes alive, my concern was that if the differential input is positive Vp > Vn,then the output of 5T OTA is held at ground level, resulting in stuck state.Vp > Vn may occur because of input referred offset of the Ampl. or perhaps during start up Vp rises faster than Vn (due to large diode cap at Vn, whereas only res at Vp). I will be grateful if you could share your thoughts on this. Thank you.
Your channel is Great

Wonderful content. WAITING FOR MORE VIDEOS
Could you make one video on noise and psrr consideration of band-gap reference?
Also is there any good reference on these as well?
Hi could u make a video on common mode rejection ratio of opamp?
looking for next video on BGR
thanks for great video again. in next video could you try to tell what is sigma value in BGR which is used commonly in industry? and how do we control it?
That will be the topic of the video #28, i.e. after the next video. Cheers.
@@analogsnippets thank you.
Just a quick question, does the dominant pole compensation here result in a LHP zero because of the series resistor?
Yes, that is correct.

HI sir i have a problem can u solve and give its emergency
