The problem are DC analysis problems. For each of the circuits verify the mode of operation and solve for all applicable DC voltages and currents. > When you "verify" a mode of operation you will need to calculate all three voltages (Vc, Ve, Vɛ for BJTS and Va, Vs, Vp for MOSFETS) and show the correct two conditions are satisfied. > Assume Capacitors acts like open circuits at DC and short circuits for AC. > Assume the following: o Beta = 100 O VBE = 0.7 o V: (Thermal) = 26 mV o Vr (Threshold) = 2V O VA = - o For MOSFET saturation mode: assume Ip = K(Ves-V7)? (Assume K = 10 mA/V*). 5V R1 3000 R2 1kn

Consider an idealized diode with a reverse saturation current 0.01 mA and an abrupt turn-on voltage of 0.7 V (assume no breakdown and operation away from the knee of the diode curve). For the circuit shown, both resistors are 100 2, the constant source is Vp = 5 V, and the time-dependent source is V3 = 20 sin(at) V. Calculate (a) the peak positive voltage V and the associated current through the diode and (b) the peak negative voltage V and the associated current through the diode. Rulamting R Vs + > KHI

When a p-and n-type semiconductor are joined at an interface their Fermi energies equilibriate. If we extend this thinking and apply it to an interface between a metal and (p-or n-type) semiconductor to make a metal-semiconductor heterojunction, what will the expected outcome be? Use diagrams and words to explain.
