Abstract

A wireless receiver circuit comprising terminals for coupling to an antenna and an impedance tuning circuit coupled between the terminals and a receiver path. The impedance tuning circuit being controllable to provide at least two impedance levels. A measurement circuit coupled to the impedance tuning circuit and configured to measure a voltage or current indicative of a signal received by the antenna for each of the at least two impedance levels. A timing circuit comprising one or more delay lines, wherein the one or more delay lines are configured to receive an initialization signal from the measurement circuit or the impedance tuning circuit. The timing circuit configured to provide one or more delayed signals to control of one or both of the measurement circuit and the impedance tuning circuit to measure the voltage or current for each of the two impedance levels.
