Abstract
Techniques are described for peak-adaptive sampling demodulation for radiofrequency transceivers. For example, a tag input signal is received via an antenna, from which a clock input signal can be extracted. Multiple clock output signals can be generated responsive to the extracted clock input signal, such that each has a different respective phase. A multiphase selector can identify the one of the clock output signals that has the respective phase that is closest to the phase of the tag input signal and is best suited for sampling the peak of the tag input signal, accordingly. A single-path detector can generate a data output signal by using the identified clock output signal to sample the tag input signal, and the detector can filter and amplify the data output signal using small-signal devices.
