Abstract
A transceiver comprising a tank circuit, a variable differential conductance, VDC, coupled to the tank circuit, and a variable resistance coupled to the VDC is disclosed. The variable resistance is arranged to bias the VDC into a region of positive differential conductance during a first state of operation of the transceiver, and bias the VDC into a region of negative differential conductance during a second state of operation of the transceiver.
