Hello All,
I am a computer science person. I am learning Analog VLSI. I have a basic question about MOSFETS. For instance, consider two NMOS transistors series connected. I have VDD = 5V, VG (dev1) = 3 = VG(dev2). Device two source is connected to ground.
\(Vdd = 5V) | |------out1 N1(gate vol=3v) | |------out2 N2(gate vol = 3v) | | gnd
If the nmos can be considered as a simple resistor with the appropriate voltages ensuring the conduction through the device, why is by out2 showing me zero (I am using cadence spectre for simulation). Should I not expect out2 current to be the drain current of N2?
I am really sorry if this question is too basic for you. I have been scratching my head over this question for too much time now..I thought you people might help me out.
Thanks, Saran
