Another way of preventing latch up is P ring around P device and N ring around N device which will act as collector and reduces the BJT collector current and hence the beta
in that case, where should it be connected? We cant leave it floating. Psub should be connected to thle most negative voltage of the design... generally 0v. otherwise there would be substrate diode or body diode forward biasing condition..meaning i connect substrate to 1V and drain of the NMOS to 0.2V, substate to drain pn junction (substrate is P and drain is N) will get fw biased. Many unpredictable things will happen... hope this answers

You Guys are amazing .. and doing awesome work
Hello sir,
You taught very well, it is great insight to learn new prevention techniques... Thank you so much sir...
Very neat explanation sir... Please continue your good work.. waiting for more videos ! 💐
Please also make video on FINFET LATCHUP.
if substrate Resistance is reduced , how is it lowering the chance of forward bias or V(be) ? Please explain
well explained Sir !!
Thanks
Why big devices has more chances of latchup in drivers?
Big devices has more Id due to that latchup can occur
if p sub is not connected to gnd , what will happen and which pblms will rise ?

@@analoglayoutdesign2342 Wil u upload video on Op-amp and LDO .
yes...but will take little time....
@@analoglayoutdesign2342 OK thanks for your response
It was very helpfull...thnk you sr.
Can we have a lecture on short channel effects in a MOSFET..... please...
yes yes...its in plan...
Super...
Thank you
Thnk u sr...it was very helpfull
If anyone needs to discuss further, please send me a text on +91 7892400015
