Abstract
ABSTRACT In a generalized operational amplifier, two-port networks are used for the input and feedback network components. By considering each one of these networks as a number of sub-networks composed of resistors and capacitors, and connected in parallel at their input as well as output ports, it is shown that it is possible to realize a minimum phase transfer function having poles and zeros anywhere in the left half of the complex frequency plane. The synthesis procedure is illustrated with an example involving a Butterworth low pass filter of order two. The stability performance of the frequency selective operational amplifier is also considered.
