Pass transistor transition response

[msdarvishi]

Dear all,

I found the transient response of a Pass-transistor using Cadence. Now, I want to calculate the transient voltage of a NMOs pass-transistor theoretically, but I got confused, any body can tell me what is the equation for transient response of a pass-transistor in its sourse?

Thanks

What do you mean by a transient voltage?

Suppose that we apply input to the drain of an NMOS transistor and connect a capacitor in its source. If we label the capacitor voltage as Vx, how can I calculate the voltage of Vx(t) in an arbitrary time while the NMOS is working in Triode region?

Thanks nitishn5

There are few good examples in chapter 12 of Razavi's book "Analog CMOS ..." that precisely answers your question.

Dear Milad,

I found the solution, thanks for your aim
