Thank you Sir 😊 for Rz the only Zero in the Ldo circuit vo/vi =1-gmpassRz-gmpass(1/SCc)= Vo=0 and then 1=gmpassRz+gmpass(1/SCc)..(1) 1=gmpass(Rz+1/SCc)..(1) (1/gmpass)-Rz=1/SCc..(1) 1/S=(Cc/gmpass)-CcRz..(1) So Wz=1/[(1/gmpass)-Rz)]Cc....Answer🤔

Thanks! Keep making more "intuition" videos. I feel like we gain valuable knowledge and skills when it comes to intuition, rather than crunching math. It would be nice to continue and explain how the transfer function would like long along with the phase shift. Primarily, It would be nice to see what a RHP or LHP affect the phase margin.

I'm not able to understand sir. How can I understand working of transistors and mosfets ? Any reference videos sir? Thank you,

Hello Amit, thank you for the analysis. I have one more comment about the wpe, wpe = 1/CL*(RFBtot||RL||rdspass), say in higher frequency, the Cc would short the gate and drain of MP, the pass devices, result in E node equivalent R = 1/gmpass. So in this case, wpe = gmpass/CL. This is usually be used as 2 stage amplifier 2nd pole analysis.
