1. Make the circuit on Fig. 4.2 using PSPICE and look for Gain and BW when C4 is 1pF.
2. Look for Gain and BW when R2, R3 values are 600 ohm at Ex.1 circuit. Explain different points compared to Ex.1 and the reason.
3. Look for Gain and BW when C4 value is changed to 10nF, 100nF, 1uF at Ex.1 circuit. Explain different points compared to Ex.1 and role of C4.

Figure 4-1. PSPICE simulation circuit
As you can see the diagram, the above diagram is the circuit which we made by using PSPICE. The left side of transistor denotes the current-mirror for supplying the constant current in counterpart transistor. This duplicated current seems to be stable compared to the any other current source. This mirrored current works to DC bias, which determines the transconductance.
