Functional Description
Inverting input resistance that sets the closed-loop gain in conjunction
1
RIN with Rf. This resistor also forms a high pass filter with Ci at fC= 1/(2
πRiCi).
Input coupling capacitor that blocks the DC voltage at the amplifiers input

terminals. Also creates a highpass filter with Ri at fc = 1/(2πRiCi).
3
Rf
Feedback resistance that sets the closed-loop gain in conjunction with Ri.
