Question

I wouls appreciate your help with the following problems. clarity is needed please. Ive tried then by my own and need to compare answers. thank you. will rate fast and positive.

#1

1.-(50) Find: Vas Im I and the region of Ro RG 15V NW 414 geration 60 mA/ 4:2V PG IMA R = 200.2

#2

thank you

Answer 1

1 ID Re 15V=VOD AVD IG=0 G - S Given circuit is N-FET. so drain will be at higher potential. In "FET." single current ID flows. UDD ID RD & VD from here, ID = ? What is t) not mentioned anything - symbols are not clear.. use Shockeley equation Io loss (1 Vp Up should be given tvp is pinch off road tage) # Condition of saturation hore Vo - VDS VD Z VGS- Up Because Rs is not present. VGS 2

Page 2 B=200 2002 + 3V TMR IB Ic + 07 V Ict IB = I E Applying KVL at input +3 = IE X 200 + Ig X106 + 0.7 IB B = Ic = Ic = 200 IB 2:3 = 200 ( Ic+IB) + IR X 106 2.3 200(200 +1EB HIB 106 2.3 (0.4x106 406) Ib 23 2B A - T.4x106 IB = 1.6 M > Ic = 2008 IB 320 MA Ic

Now, Dote Page KUL" at at output +ICE 3 Ie X200 (Ict IB) 200 + VCE 397-6x200x106 FDCE 35 0.643 + VEE VCE 2.357 v calculated Ice We have uchich is (cactive = 320 MA Let's check, in which region BTT is working for that have to calculate (Ic) SAT 3 2.357 (Ic) SA we SAT 200 BUT in (Ic) gp 3215 48 so here (Ic) Active (IC) SAT CActive Region
