Hello:
I want to change some characteristics of a mosfet that come in the Sedra Pspice library, how do I make that?. I supose the right way is editing the model and changing the values.
The problem is that there are way more parametres than those I know. I only want to change K,Vt from : ID= K * (Vsg-abs(Vt))^2. From Sedra K=1/2 * Cox * W/L.. can't identify these values in de following model.
* Level-1 Model for PMOS in model 5um CMOS Technology
* (created by Anas Hamoui & Olivier Trescases)
.model PMOS5P0 PMOS(Level=1 VTO=-1 GAMMA=0.65 PHI=0.65
+ LD=0.6E-06 WD=0 UO=250 LAMBDA=0.03 TOX=85E-9 PB=0.7 CJ=0.18E-3
+ CJSW=0.6E-9 MJ=0.5 MJSW=0.5 CGDO=0.4E-9 JS=1E-6 CGBO=0.2E-9
+ CGSO=0.4E-9)
the capacities are evident I think.
Regards
