Question

Determine the mode of operation (saturation, linear, or cutoff) and drain current ID for each of the biasing configurations given below. Use the following transistor data: NMOS: k'n= 115uA/V2, V70 = 0.43 V, PMOS: k'o = 304A/V2, V70 = -0.4 V. Assume (W/L) = 1. (1) NMOS: VGS = 2.5 V, Vps = 2.6 V. (2) PMOS: VGS = -2.5 V, Vps =-1.8 V.

Answer 1

The mode of operation and drain current for each biasing configuration can be determined using the given transistor data and equations.

Step-by-step explanation:

The mode of operation and drain current for each biasing configuration can be determined using the given transistor data and equations.

1. NMOS: VGS = 2.5 V, Vps = 2.6 V
   Mode of Operation: Linear
   Drain Current: ID = (k'n/2)((VGS-V70)^2 - (Vps-V70)^2) = 0.148 mA
2. PMOS: VGS = -2.5 V, Vps = -1.8 V
   Mode of Operation: Cutoff
   Drain Current: ID = 0
