Abstract: A wireless receiver receives a wireless signal by inverting the polarity of an incoming waveform on every one half clock cycle of a conversion clock to produce a commutated waveform and converting said commutated waveform to a series of representative digital values using a delta-sigma modulator clocked by said conversion clock. In this way, the receiver operates over a large dynamic range and the use of automatic gain control in the front end may be eliminated.
