Question

For W/L=50/0.5, and abs(Id) =0.5mA, calculate the numerical value for the transconductance (gm) of both NMOS and PMOS devices. Use the parameters provided in table 2.1 of Razavi's book.

Circuit diagram is not needed as the gm equation uses only Id. How do I find Cox from the information below?

Level 1 SPICE Models for NMOS and PMOS Devices. Table 2.1 NMOS Model PHI-0.9 LAMBDA- 0.1 VTO 0.7 LD-0.08e-6 PB = 0.9 MJSW= 0.2 GAMMA = 0.45 UO = 350 CJ 0.56e-3CJSW CGDO=0.4e-9 LEVEL1 NSUB = 9e+14 0.35e-11 JS = 1.0e-8 MJ = 0.45 PMOS Model VTO--0.8 GAMMA 0.4 PHI 0.8 LD=0.09e-6 PB 0.9 MJSW 0.3 CGDO 0.3e-9 JS - 0.5e-8 LEVEL1 NSUB=5e+14 TOX = 9e_9 MJ-0.5 LAMBDA = 0.2 CJSW- 0.32e-11 UO=100 CJ 0.94e-3C
