High Q complex pole realization by RC active network synthesis.

Abstract

The realization of a transfer impedance with a single complex pole pair through RC active synthesis has led to applications in low pass circuits . One active source properly loaded will have the same percent change in its equivalent elements as the passive resistances and capacitances which complete the circuit,. The technique of adding additional active sources to obtain high Q complex pole pairs for bandpass applications is derived» Methods of loading the several active sources to restrict their variations are given„ Limitations of the synthesis for very high Q"s are discussed. and some interesting aspects of the final circuitry pointed out.
