An NPN bipolar junction transistor having VB > VE and Vc = (VB-400 mV) is: Select one: a. Operating in saturation. O b. Operating in deep saturation. c. Operating in active mode. O d. Operating at the edge of soft saturation.

Determine vo versus v₁ for the circuit shown in Figure 2. Assume that the MOSFET operates in saturation and is characterized by the parameters K and VT. Vs R₁ www Figure 2 wwww RL R₂ wwwww VO Note: assuming the MOSFET works at normal saturation regime and ips= (VDS -VT)²2 K 2

Please all subpart is compulsory for like this please Asap

Can someone explain this problem to me. I don't know how to get to the answer that is given.
