Inverting OP Amp
- Construct the inverting amplifier according to the wiring diagram below.
- insert a 0.1 F capacitor between ground and the OP power supply input pin.
Gain measurements
- Measure the gain as a function of frequency between 100 Hz and 2 MHz for three values of R_2 = 10 k, 100 k, 1M.
- Graph the above measurements with the Gain in units of decibels (dB) and with a logarithmic scale for the frequency axis.
Impedance
Input Impedance
- Measure for the 10 fold and 100 fold amplifier at ~100 Hz and 10 kHz frequency.
Output Impedance
- Measure for the 10 fold and 100 fold amplifier at ~100 Hz and 10 kHz frequency. Be sure to keep the output () undistorted
