As the filter is frequency selective network, the output Vo(t) contains only some of the frequency components of Vin (t). It is convenient to analyze the filter by representing it in a frequency domain as shown in Fig. 3.5.1 (b). In the frequency domain, the filter is described by the transfer function,

Miller Effect Compensation | Op-amp
Subject and UNIT: Linear Integrated Circuits: Unit II: Characteristics of Op-amp
A capacitor ranging from 10 to 30 pF is fabricated between input and output stage to achieve the necessary compensation. This type of compensation is called Miller effect compensation. Such op-amps are called compensated op-amps.
