Very detailed explanation 👌 When t=0+, both S1 and S2 are closed And the three capacitors are marked with initial values and are connected in parallel. so (2*2+3*4+4*3)=vx*(c1+c2+c3)=9vx 28=9vx,vx=28/9 v I have a stupid question, where is this circuit used?😮

I am a 3rd year student of jadavpur University EE dpt. I watched your mock interview videos of two candidate who were selected in Lemon Flip. I am preparing for analog vlsi domain. So how can I appear in a same kind of mock interview session to test how much prepared I am ? Could you please tell me? 🙏

this is the Maximum voltage , what about the minimum voltage..is there any way to evaluate the minimum voltage for this example
@AllenSA_Lymangirl 4 күн бұрын
Awesome! But the time constant will be different! Case 1: Vc(t)=IR2*(1-e^-t/(R1+R2)*C) Case2: Vc(t)=IR2*(1-e^-t/R2*C) And then case1vs case2 are RC charge circuit but case 2 RC charge Speed close to steady state vo is better than case 1

Explain very clearly Sir👍 Very simple conpect Ad=-gm1*(ro3//R) and CLM=0 then ro3 infinity So -gm1*R.....Answer Ac=vo/vcm= 1/gm3*(-gm1/(1+gm1*2Rss)....Answer and hope to reduce to Zero ideal Why R must be shorted for Ac🤔

If you do a little bit of calculation you will find that the node voltage Vs1 has to be in the range of 3.333 to 4. Therefore how can you surely say that Vs1 is at 4 volt ?

Hi, Please explain why you are adding rds1 and rds2...Cascode means we have rds1 product of rds2 right?
@guhanrajasekar5993 13 күн бұрын
At 2:41, you say that Vs1 = 4V. That is just the max possible value of Vs1 right? How do you conclusively say that the node voltage Vs1 is 4V?
@shreymaru1613 13 күн бұрын
Same doubt
@guhanrajasekar5993 13 күн бұрын
@@shreymaru1613 I think here he makes the assumption that Width of the transistor is extremely high. So, for a fixed current, if W keeps on increasing, the overdrive voltage Vgs-Vth keeps on reducing. Theoretically, if W tends to infinity, the overdrive voltage Vgs - Vth tends to 0 to keep the current fixed. So, if Vgs - Vth = 0 => we get Vgs = Vth.

You can quickly see that it’s 5 - 3*vt = 2V/2k = 1mA
