Hi every one
PLZ can any one help me for these equations :
I now design tow-stage OP-AMP by using ORCAD(PSPICE) simulation so my equations are:
1-what are the names for transistors (PMOS ,NMOS)that must used?
for examble(POWMOS,breakout,...,etc) that i take it from Library.
2-from where i get the parameters that will be inside the transistors for examble(COX,TOX,Kp,Kn,....,etc)
Note: i design for level 1 with Process 1um.
3-when I compute the(Cgs,cgd)the equation is the values for(Cgs,Cgd)will take as:
Cgd=W*Cox*Xov or Cgd=Cox*Xov the same as for Cgs.
becous thess values for capactances will be inside transistor paramerters in PSPICE.
PLZ I quation so much for Cgd and Cgs these take as Cgd=W*Cox*Xov or Cgd=Cox*Xov the same as for Cgs.
