11.2 Instrumentation Amplifier Analog Simulation with MPLAB® Mindi™
In MPLAB® Mindi™, open Instrumentation_Amplifier.wxsch schematic from the GitHub repository.
The circuit shown in the left half of Figure 11-4 is driven by a 25 Hz, 256 mVPP sinusoidal differential signal source with 825 mV DC offset. The op amps are powered by a 3.3V voltage source.
Simulate by selecting; Simulator → Run Schematic or press Function Key F9. The resulting simulation output graph is shown in the right half of Figure 11-4. It can be noticed that the output signal (in red) is three times the input signal (in green), while keeping the signal in phase.
