Design of Integrable Desensitized Frequency Selective Amplifiers

Synthesis procedures are presented for the synthesis of prototype frequency selective amplifiers suitable for semiconductor integrated circuit realization. Constraints and degrees of freedom imposed by semiconductor integrated passive and active components are incorporated in feedback amplifier designs. In order to achieve desensitized response, first-order pole-sensitivity functions are used in the synthesis. This leads to procedures for the simultaneous realization of prescribed response and response invariance. The procedures require feedback structures with redundant transmission-loops to provide extra degrees of freedom needed in the design. Experimental results from prototype amplifiers are presented.
