Given:
VTN=1V Kn=0.5mA/V2 λ=0.01V−1
To Find:
- VGSQ & VDSQ
AV, Ri, R0
Equation ckt of above can be redrawn for DC analysis
Solution: In Mosfet, ID=IS=4mA
IG=0(reverse biased)
Applying KVL
-VGSQ+5V=0
VGSQ=+5V
VDSQ=VDD-IDRD
=5-(0.4)(10)
=1V
- For Mosfet:
gm=Kn(VGS-VT)
=0.5(5-1)=2
Equation ckt for ac analysis: deactive all dc sources & replace …
