Final answer:
To compare an op-amp in inverting and non-inverting modes, perform measurements of input impedance, power consumption, amplifier gain, and bandwidth using a DC voltmeter, ammeter, and oscilloscope in Multisim, while ensuring the correct connection of measuring instruments according to Ohm's law and other pertinent electrical principles.
Step-by-step explanation:
To compare the characteristics of an operational amplifier (op-amp) in both inverting and non-inverting modes using Multisim, you would perform tests to measure the following parameters: input impedance, power consumption, amplifier gain, and bandwidth. Here is a series of tests you can follow:
- Input Impedance: To measure input impedance, apply a known voltage and measure the current going into the input of the op-amp. Use Ohm's law (V=IR) for this calculation.
- Power Consumption: Connect a voltmeter across the supply voltage of the op-amp and an ammeter in series with the power supply to measure the current. Multiply voltage by current to determine power consumption.
- Amplifier Gain: Feed a sine wave or DC voltage to the op-amp and measure the output voltage. The gain is the ratio of output voltage to input voltage.
- Bandwidth: Apply a sine wave of varying frequencies and measure the output voltage until it falls to 70.7% (or -3dB) of the maximum output voltage. This frequency is the bandwidth limit.
During this process, use a DC voltmeter for voltage measurements, an ammeter for current measurements, and potentially an oscilloscope to observe the wave shape and amplitude changes. It's important to follow the correct procedure for connecting measuring instruments: a voltmeter should be connected in parallel with the component being measured, while an ammeter should be connected in series.
