nickagian Posted August 15, 2006 Report Share Posted August 15, 2006 Hello everybody! I have to complete a design of an OpAmp using CMOS technology and the given model for the nMOS transistors is the following:.model Mn NMOS(LEVEL=2 LD=0.1e-6 VTO=0.77 KP=77e-6 GAMMA=0.35 PHI=0.76 CJ=0.31e-3+CJSW=0.17e-9 CGSO=0.19e-9 CGDO=0.19e-9 CGBO=0.3e-9 NSUB=1.9e16 NFS=1e10 TOX=200e-10+XJ=0.14e-6 UCRIT=1.5e4 UEXP=0.077 DELTA=2 KF=4e-13 AF=1.2)My problem is that I am not sure what exactly is the formula that computes the Idrain of the MOS.Of course we know that in saturationID=k*(W/L)*(VGS-Vth)^2, where k=K/(1+ Quote Link to comment Share on other sites More sharing options...
