Im trying design this function : (NOT Y)=A+BCD in CMOS my design in pic below now i want to design this function in Pseudo NMOS but i dont know how to design it in Pseudo NMOS.anyone can help please??
The name ``pseudo-NMOS'' originates from the circumstance that in the older NMOS technologies a depletion mode NMOS transistor with its gate connected to source was used as a pull-up device. http://www.iue.tuwien.ac.at/phd/schrom/node101.html
Pseudo-NMOS isn't totem pole output, just add a small PMOS pull-up.
Note: Depletion mode refers to the channel being inverted at Vgs = 0, similar to a typical JFET, you use the gate to pull the device out of conduction.
