Inverting OP Amp

1. Construct the inverting amplifier according to the wiring diagram below.
2. insert a 0.1 [math]\mu[/math]F capacitor between ground and the OP power supply input pin.

Gain measurements

1. Measure the gain as a function of frequency between 100 Hz and 2 MHz for three values of R_2 = 10 k[math]\Omega[/math], 100 k[math]\Omega[/math], 1M[math]\Omega[/math].
2. Graph the above measurements with the Gain in units of decibels (dB) and with a logarithmic scale for the frequency axis.

Impedance

Input Impedance

1. Measure [math]R_{in}[/math] for the 10 fold and 100 fold amplifier at ~100 Hz and 10 kHz frequency.

Output Impedance

1. Measure [math]R_{out}[/math] for the 10 fold and 100 fold amplifier at ~100 Hz and 10 kHz frequency. Be sure to keep the output ([math]V_{out}[/math]) undistorted
