Abstract:
A radio frequency (RF) receiver having an analog gain control section for controlling the gain of a received RF signal, and a digital demodulator section for demodulating the output of the gain control section, includes an analog GO circuit connected to recognize the presence of a data packet within a received RF signal in the analog gain control section, and in response to produce an analog GO signal, a digital GO circuit connected to recognize the presence of a data packet within the received RF signal from the digital demodulator section, and in response to produce a digital GO signal, and control circuitry connected to enable gain control functions within the analog gain control section and digital demodulator functions within the digital demodulator section in response to respective analog and digital GO signals.
