# Circuit Analysis - Calculating Voltage

Please refer to the attachment questions and diagrams. Questions are asking to calculate overall resistance, voltage, and finding the values for input impedance and output impedance.

l. Assume the transistor you will use has a beta of 155 and V_BE(on)=0.65 V. For the circuit in Fig. 2. (attached) calculate the overall resistance (R_B and pot) such that I_C = 1 mA.

2. Compute the voltage V_c.

3. Find the values for the input impedance R_i, output impedance R_o, and small signal transcouductauce g_m.

4. Find the value of the small signal voltage gain.

5. Construct the circuit in Fig. 2 in Pspice and ﬁnd the small signal parameters g_m and R_ce. Compare SPICE results and hand calculations. Explain the differences, if any.
