1. 실험목표
1. To study current mirror circuits which offer bias from the reference current/voltage source.
2. To observe the pros and cons of the basic current mirror circuit and cascode current mirror circuit.
3. To observe the pros of the Wilson current mirror which adopts the negative current feedback.
2. 실험과정
(1) NMOS Current Mirror:
1. Construct the basic current mirror circuit with two terminal outputs shown in Figure, using the CD4007 CMOS array and set the power supply voltage to +15V.
2. Measure the terminal voltage at A to E using the multimeter. Then measure or calculate the current ii, io1, io2. Calculate the current transfer ratio of input current in and output current io1, io2
3. Short R2B and measure the voltage at node D and current io2. After connecting R2B, measure the voltage at node D and current io2 then calculate output impedance using the voltage and current change.
4. Make R1B Short and repeat step 3 to calculate the output resistance value of Q2(w.r.t node B).
(2) Cascode Current Mirror:
1. Construct the cascode current mirror circuit shown in Figure.
