Illustration and explanation here make the formulas looking much more comprehensible, unlike those same ones appear in the textbook. Great job. Many thanks.

[@richardsmith813]

I use LTSpice (latest free version) and basic NMOS with .model nmos1 nmos(vto=0.5 kp=200e-6 l=100u w=100u lambda=0.02) statement , name all my NMOS as nmos1, then do DC sweep using source to sweep as Vd3 .dc 2.5 6 .1 and I can replicate all your Multisim easily. Thank you for your detailed description of this and the derivation of the formulas step by step.

[@prasasus]

Wow! This channel is so underrated !! Love your explanation sir...

[@ofek2852]

sir you are a legend! thank you for these amazing videos

[@mayurshah9131]

VERY WELL EXPLANATION 👍👍

[@廖斯宇-r7b]

This class helps me a lot. thanks!

[@venti0616]

thank you sir, you have saved my life.

[@btimabader2866]

hi, we really appreciate the time you take to share this important information with us. i liked your learning approach. and i wish if you can make a video about MOSFET high frequency model. thanks

[@ALLABOUTELECTRONICS]

Soon it will also be covered.

[@marklee8046]

Exactly the video I needed, thank you

[@sagarraj4521]

Thank you sir. Best explanation..

[@pavankumarkori715]

yeah i like your video your explanation are very fine good work sir

[@EaseJoy44]

Bro .. Please we need videos about Semiconductors / Optoelectronics I love your channel

[@vimakuma]

Hi I have a question. What if I use a resistor between gate and Drain connection of diode connected transistor. Will it be still the current mirror..

[@abdullah376-]

Great!!! What happens if we have a drain resistor on the cascade mirror side?

[@aadilabbas1397]

thank you, very helpful

[@pavankumarkori715]

the nice explanation at the end of the video you said there is some downside of this circuit in ac analysis like voltage swing and operating point so for remove that issue what we should can you make video on that also with simulation so we understand better one suggestion can you make a video on ,single and two-stage opamp with current mirror circuit

[@parkercampaige6593]

Sir it would be very helpful if you explain the topics from Razavi Sir's book the "Modification of cascode mirror for low-voltage operation."(5.18) topics it creates a lot of confusuion.,actually i want to know what will happen if we connect the gate of M1 to the drain of M4.

[@robr8554]

Can you do a bjt current mirror used a Current sense to measure the high side current of a load running up to 32A

[@giuseppetrematerra8572]

Hello Sir, really nice video, appreciated for real the explanation. I just wanna ask a quick question to understand clearly. If my cascode current mirror has all the MOSFETs working in saturation mode and I am not considering the modulation of the channel, in order to raise the output resistance, should I just focus on the W/L ratio of the MOSFETs? In particular, if I am not wrong, I should probably increment the W of the MOSFETs, right? Please correct me if I am wrong

[@satirthapaulshyam7769]

1:00 cz ur roi=infinite so rout=ro || roi = ro . So gain is gm* ro When current mirror comes the gain reduceed to gm* (ro1||ro2)

[@pavankumarkori715]

MY COPY CURRENT IS CHANGING WHEN I VARY VD3 Value what should I do now?

[@tomc642]

Hope you do the MOSFET Differential Amplifier.

[@ALLABOUTELECTRONICS]

Yes, will also make a video on it someday

[@pavankumarkori715]

sir in the video I see that your voltage is varied +-(2v) to (3v) current is same but when i am doing simulation in lt-spice when I vary my voltage Vd3 +-(0.5v) to (1v) it's current change drastically what should I do now, how I share my simulation thing?

[@ALLABOUTELECTRONICS]

What is the channel length modulation parameter? Please check the value of lambda (λ) of the MOSFET that you have used during the simulation. You can mail me if required. you will find the email id in the about section.

[@Darin-sn9yv]

What is used simulation program? It looks very intuitive

[@ALLABOUTELECTRONICS]

It’s multisim

[@shreyapervaje9093]

Thank you :)

[@user-saint]

Thanks a lot!

[@xuezhizhang5566]

Can we have a video explains Wilson current mirror? Thanks!

[@pavankumarkori715]

HELLO SIR SAME THING I TRY IN LTSPICE BUT IN MY CASE WHEN I TRY TO SWEEP VD3 IT'S VALUE ARE CHANGING FROM 2u TO 8u

[@MrBubblegumx]

what is the name of the program youre using at 2:20 ?

[@ALLABOUTELECTRONICS]

Multisim

SIR, I TRY WITH CHANNEL LENGTH 16NM BUT IN MY CASE COPY CURRENT IS Vary what should i do

Ok, I will send you the simulation link of multisim.
