Op amp circuit diagram

There are two basic types of amplifier circuits: noninverting amplifier and the inverting amplifier. Their AC-coupled version is shown in Fig. For AC circuits, reverse means that the phase angle is moved in 180 degrees. This circuit uses a coupling capacitor-Cin. Cin is used to prevent circuit DC amplification, so the circuit will only produce amplification oon AC. In the DC circuit, Cin is omitted, then it must be calculated on the DC amplification. In the high-frequency circuits, it is very important to violate the op amp's bandwidth limitations or not.
