Question

3. Connect the capacitors and the load resistor as shown in the figure below. For V1 us a 5 kHz sine wave and adjust the amplitude so kant of the amplifier (across RL) is at its maximum (with no clipping, of course). Use the Tektronix oscilloscope to measure V, and kauhe Sketch V, and Laute on the same oscilloscope window below showing voltage and phase. Clearly label the scale for both axes. In a physical lab we would also note: If the amplifier starts to oscillate then try keeping the input and output scope leads well separated and connect 0.01 uF capacitors from Youn to ground. We do NOT need to do this in our simulation. VCC 20.0V Xsci (RB 470k Tektronix C2 HH 10F Q1 2N4124 c1 V1 HE 10uF RE 2.2k RL 1ka I

Answer 1

here is the simulation results:-

Voltage gain= V_out / V_in

= 695.56 / 707.21

Voltage gain A_v = 0.9835
