Hi, I am trying to get Noise Figure in track and hold circuit with RC>>Ts/2 as shown in added image.
NF= 10logF, where F is Noise Factor and F = (Ni+Nsys)/Ni.
In my circuit Nsys =0 (Sys include only switch and cap, there is no res(noise generator)). so, F should be =1, so the Noise figure should be = 0. But, cadence giving me F = 1.96 and NF = 2.92.
Please help, what I am doing wrong. I have added image of schematic and setiing of PSS and Pnoise
