Abstract
The present invention provides methods and apparatus for controlling power utilization in a wireless communication receiver. A representative system comprises a signal properties evaluation module, an analog to digital converter (ADC), and an analog to digital converter control module. The signal properties evaluation module evaluates the stability of a received signal, and provides an indication of the stability. The ADC control module responds to the signal properties evaluation module to select the precision of the ADC based upon the indication of the stability. The ADC has at least two modes of operation, comprising a first precision and a second precision, and is responsive to the signal properties evaluation module to operate in at least one of two modes based upon the stability. The ADC responds to the signal properties evaluation module so as to limit the amount of power consumed by the wireless communications device.
