Abstract
A demodulator including a peak sampler to control an ADC or a digital resampler to sample a carrier signal in an unmodulated state at peaks, and to sample the carrier signal in a modulated state at a phase of the unmodulated state; and an envelope builder to determine an envelope signal based on differentials between maximum and minimum peaks of respective cycles of the sampled carrier signal. Further, a demodulator having an offset estimator to estimate in-phase and quadrature components of a carrier signal in an unmodulated state to determine in-phase and quadrature component offsets; a load modulated signal estimator to estimate in-phase and quadrature components of a load modulated signal by removing the in-phase and quadrature component offsets from in-phase and quadrature component samples of the carrier signal; and an envelope builder to build an envelope signal by combining the in-phase and quadrature components of the load modulated signal.
