Abstract
The invention described herein is directed to different embodiments of a wireless communications device that can be used in many different applications, such as but not limited to a digital oversampling receiver adapted to select desired signals and to reject undesired signals. In one embodiment, a wireless communications device is disclosed that comprises an architecture for a receiver front end that obviates the need for high order passive circuitry or RC active circuitry to select desired signals and to reject undesired signals.
Claims4
A method of receiving a wireless transmission comprising the steps of:
- programming a count pattern into an N stage ring counter, wherein N is an integer of value greater than one;
- producing an N-cycle digital waveform;
- combining said N-cycle digital waveform with said wireless transmission;
- oversampling said combined digital waveform and said wireless transmission to form a high speed serial stream, said high speed serial stream comprised of a signal of interest and a quantization noise signal;
- suppressing said quantization noise signal;
- and
- converting said high speed data stream into a lower speed.
