). Simulate the circuit in any of the packages you have identified in the first assignment, and then assess the performance of the software package by carrying out mathematical analysis of the circuit.
Op Amp Summing Amplifier
For this simulation an Op amp summing amplifier has been used, this kind of amplifier has a virtual earth point, which allows the use of different number of voltages (d.c. or a.c.). This characteristic makes them suitable for diverse use such as “mixer” in audio systems to combine the output of microphones, electrical guitars, etc. Op amp summing amplifier is also used to perform mathematical calculations in analogue computing.
Op Amp Summing Amplifier Simulation 1

Circuit Values
v1=2mV Frequency:1kH
v2=1mV Frequency:1kH
RFeedback=10kΩ
vout=-3mV

Fig 1.1 Op Amp Summing Amplifier
Output Voltage
v1R1+v2R2=-voutRf →vout=-Rf(v1R1+v2R2)

Substituting for peak values vout

Fig 1.2 Op Amp Summing Amplifier

vout=-10kΩ(2mV10kΩ+1mV10kΩ)
vout=-10,000Ω(0.002V10,000Ω+0.001V10,000Ω)
vout=-31000=-3x10-3=-3mV

Op Amp Summing Amplifier Simulation 2

Circuit Values
v1=2mV Frequency:1kH
v2=1mV Frequency:5kH
RFeedback=20kΩ
vout=-6mV

Fig 1.3 Op Amp Summing Amplifier

Fig 1.4 Op Amp Summing Amplifier

Output Voltage
v1R1+v2R2=-voutRf →vout=-Rf(v1R1+v2R2)
Substituting for peak values vout

vout=-20kΩ(2mV10kΩ+1mV10kΩ)
vout=-20,000Ω(0.002V10,000Ω+0.001V10,000Ω)
vout=-3500=6x10-3=-6mV

Results Simulation 1 & 2

An Op amp summing amplifier circuit with 2 input voltage v1:2mVand v2:1mV in a.c. applied via R1/R7 with 10kOhms resistance and R2/R8 with 10kOhms resistance and 2 voltage sources v3 & v4 with 15 volts d.c. simulation 1 and 2 (fig: 1.1 & 1.3).
In Simulation 1 (fig: 1.1) the value for the feedback resistance ( Rf ) is 10kOhms whereas the In Simulation 2 (fig: 1.3) the value for the feedback resistance ( R11 ) is 20kOhms.
Using the formulas vout=-Rf(v1R1+v2R2) the 2 inputs voltages (v3 & v4) are added and amplified if Rf/R11 is greater each of the input resistors there is a voltage gain. With the use of the previous formula, it has been possible to contrast the results from Orcad simulation (fig: 1.2 & 1.4) to the mathematical calculation for a Summit Amplifier, in which the results has been the same.
As it can be seen in both mathematical calculation and Orcad simulation there is a gain difference in vout from circuit Op Amp Summing Amplifier 1 (fig: 1.1) which uses a 10kOhms resistance and circuit Op Amp Summing Amplifier 2 (fig: 1.2) which uses a 20kOhms resistance. The vout gain is proportional to the increase in feedback resistance going from –3mV using a 10kOhms resistance, to -6mV for a 20kOhms resistance.
Another differential characteristic that can be seen contrasting both simulations (fig: 1.2 & 1.4) is from the fact that in circuit Op Amp Summing Amplifier 1 (fig: 1.1) both v1:2mV and v2:1mV have a 1kHertz frequency whereas in circuit Op Amp...
