ABSTRACT:
Various embodiments are disclosed relating to techniques of filtering and down-converting a received signal. In accordance with an example embodiment of the present invention, an analog signal may be received and amplified in a transconductance amplifier. The amplified signal may be connected to a switching arrangement and an impedance circuit connected in series, and frequency down-converted in a second circuit. The resulting analog base band signal may be fed back to a base band input between the switching arrangement and the impedance circuit.
