The inverting and non- inverting amplifier configurations responds to both ac and dc signals. However if we want to get the ac frequency response of an op amp or if the ac input signal is superimposed with dc level, it becomes essential to block the DC component. This is achieved by using an AC amplifier with a coupling capacitor.AC amplifiers are of two types, inverting and non inverting types Inverting AC Amplifier The circuit shown in fig 4.6a, the capacitor C blocks the dc component of the input and together with the resistor R1 sets the lower 3dB frequency of the amplifier AC AMPLIFIER
