Radio-frequency apparatus with improved power consumption and associated methods

Abstract:

An apparatus includes a radio frequency (RF) receiver, which includes a differentiator to differentiate a phase signal to generate a differentiated signal. The RF receiver further includes a correlator coupled to receive and correlate the differentiated signal, and a memory to receive and store the differentiated signal. Samples of the differentiated signal are provided to the correlator and to the memory synchronously.
