3. In the circuits shown in Fig. 3, transistors are characterized by |V|=1V, kp' (W/L)=4mA/V², λ=0. Find the labeled voltages V4 through V7 +5V ⑦2 mA -OV₂ -5V (c) 1.5 k +5V Fig. 3 (d) -0% V6 2 mA

1) please solve with work, will upvote!

An npn transistor with IS = 1 × 10−16 μA, αF =0.975, and αR = 0.5 is operating with VB E = 0.70 Vand VBC = 0.50 V. By definition, this transistor isoperating in the saturation region. However, in thediscussion  it was noted that this transistor actually behaves as if it is still in the forwardactive region even though VBC > 0. Why? Use thetransport model equations to justify your answer

For the circuit shown below, find the value of R that results in Vp = 0.8 V. The MOSFET has VTh = 0.5 V, H,Cox = 0.4 mA/V2 , W/L = 0.72 um/ 0.18 um , and A = 0 +1.8 V R o Vp Select one: O a. 150 KO O b. 34.4 Ke O c. 7 KN O d. None of these.
