1. What is Current Mirror circuit ? Why is it so called? Draw a three MOSFET two stage current mirror and explain how the reference current equals the drain current of the second stage MOSFET.

Pls help ASAP. Pls show all work.

QUESTION 4 a) Discuss four advantages of field effect transistor (FET) over bipolar junction transistor (BJT). b) With the aid of suitable diagrams, explain the primary difference between n-channel depletion and enhancement type metal oxide semiconductor field effect transistors (MOSFETS).

What is the approximate range for the base-emitter Zener voltage in a BJT and why is the range not smaller nor larger?

Draw the IV graph for a MOSFET in deletion mode, with a drain source current of 1.2 mA. Indicate this value on the graph

2. Determine the VCB (i.e., voltage difference between collector C and base B) in the transistor circuit shown in the figure below. The transistor is silicon type (i.e., VBE is 0.7V) and has current gain hEE- 150. (Assume the transistor is working on active region) Rc 100 2 RB 10V Vcc 10 k2 VBR = 5V

State and explain the relation of drain current versus gate to source voltage for an MOSFET.

A PWM signal changes with a voltage of -15 and 15 volts while it is desirable to produce an effective (average) voltage of the PWM signal of 9 volts. The duty cycle that must be generated is
