Abstract
A single chip superheterodyne AM receiver is disclosed herein. The receiver has a control pin for application of control signals to adjust a frequency response of a baseband filter to tailor its frequency response to a particular type of signal received by the receiver. Various techniques are described for enabling a complete superheterodyne AM receiver to be implemented on a single chip which receives an antenna input signal and outputs a digital data signal.
