Question

1-(50) Find: RG 15V - Yas , Im and the region of goeration km = 60 mA/v? =2V M 1 - 2 PIM2 Po = 2002 tid I Is Vee and the region

Answer 1

solution- 10 given kn= Goma/u2 Rq Rs 15V Vt = 20 VD va Igao vs Ra=ime Ro= 2002 Yin, assum MOSFET operate in saturation mode. VDS > Nas-ut SD, ID = Yakn (vas.uty? 10 = y*60x163 (Vq5-27? Vas= va-vs= 15-R.DID-0 = 15-RDID Nas= 15-20 10 19 30x10-3 (15-20010 -2)? 10 30x103 (169 +4x60410 - 5.28161D) ID: 5.07 +1900 I'D -1561 D 1200 ID jo -157 1D + 5.07= 0 ID = 72.7mA, 58.0AMA x but vas> vt for operating MOSFET so ID=58.04 mA

Vasa 15- IDRO X200 215 - 58.0 AX103 Vas : 3.392 v 9м. 19 ܕ &x 58.04x16-3 3.392-2) (195-vt) gma - 0.11608 1.392 83.AMA/ and VOSE 15- Rolos 15- 58.04710?x200 3. 1921 and Nascut = 1.3921 So, NDS?, Vascut. region of operation is saturation region.
