Design a multistage voltage amplifier in pspice for the following specifications:

1. Voltage Gain > 100 V/V

2. Input resistance > 108 ohms

3. Output Resistance < 200 ohms

4. D.C. Voltage Source ±5 V

5. Output peak to peak voltage swing > 5 V

6. Use minimum number of resistors.

7. Number of active devices not to exceed 15. You can use more devices if you use current sources.

8. Channel length (L) = 0.8 μm, (W/L)min = 1, (W/L)max = 100
