Part B: Inverting Operational Amplifier (Op Amp)
⚫
The inverting amplifier (Figure 9) has a gain magnitude that can be less than 1 (unlike the non-inverting
configuration where the gain will always be greater than or equal to 1).
• One complication with the inverting amplifier is that the input impedance is rather low (approximately
R1), and that the gain of the circuit can be influenced by the output impedance of the signal source.
