    Abstract

    This paper presents a novel approach to the design of integrated reconfigurable and programmable analog filters for commercial mobile applications. The method is described in the specific context of an analog filter which is capable of operating in both the complex and real domains; the filter is designed using the OTA-C technique, features a programmable order and transfer function and is envisioned as part of a combined low-IF/zero-IF receiver architecture for a software defined radio transceiver. The novel method is demonstrated by presenting the simulation results of the real low-pass/complex band-pass filter for a 0.5~dB Chebyshev approximation.
