Conversion of a MISO Filter into its Reconnectionless Reconfigurable Form with Complex Active elements

Abstract

This paper aims to show an easy way how to design a reconnection-less reconfigurable filter based on the modification of an existing MISO filter. The proposed filter offers the same transfer functions as the structure before the modification and additionally offers function of the direct transfer and high-pass function with transfer zero. In comparison with the structure before the modification, the proposed filter provides the electronic control of its pole frequency and quality factor. The design is supported by simulations in Cadence IC6 (spectre).This paper aims to show an easy way how to design a reconnection-less reconfigurable filter based on the modification of an existing MISO filter.
