Abstract
A power detector for use in an RF receiver. The detector includes a power reference generator and a power quantizer. The power reference generator develops a power reference current, voltage, or signal as a function of a power transferred via a received RF signal. The power quantizer is responsive to the power reference current, voltage, or signal to develop a digital field power value indicative of the power reference current, voltage, or signal.
Claims7
A power detector for use in an RF receiver, the detector comprises:
- a power reference generator adapted to develop a power reference voltage as a function of a power transferred via a received RF signal, wherein the power reference generator includes:
- a regulator circuit adapted to develop a first current proportional to the power transferred via said received RF signal;
- and
- a reference circuit coupled to the regulator circuit and adapted to develop said power reference voltage as a function of said first current;
- and
- a power quantizer, responsive to the power reference voltage, adapted to develop a digital field power value indicative of said power reference voltage.
