Abstract:
Various embodiments are disclosed relating to a gain control for a wireless receiver. In an example embodiment, a wireless receiver is provided that may include an analog gain circuit adapted to provide a variable analog gain on a received input signal, an analog to digital converter (ADC) having an input coupled to an output of the analog gain circuit, and a digital gain circuit having an input coupled to an output of the ADC and adapted to provide a variable digital gain on a received digital signal from the ADC. According to an example embodiment, the wireless transceiver may decrease a gain of the analog gain circuit while maintaining a gain of the digital gain circuit substantially constant for a receiver input signal level that increases from a first input signal level up to at least a first test signal level. In addition, in an example embodiment, the wireless receiver may also decrease a gain of the analog gain circuit while maintaining a gain of the digital gain circuit substantially constant for a signal level of the input signal that increases from a first input signal level up to at least a blocker test signal level.
