Claim:
1. A transceiver comprising: a tank circuit, a variable differential conductance (VDC) coupled to the tank circuit, and a variable resistance coupled in series with the VDC, and 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, wherein the VDC is coupled to the tank circuit such that the positive differential conductance of the VDC during the first state of operation of the transceiver prevents the tank circuit from oscillating, and the negative differential conductance of the VDC during the second state of operation of the transceiver allows the tank circuit to oscillate, and wherein the variable resistance is adapted to be controlled by an electrical trigger signal with a first slew rate for operating the transceiver in transmitter mode, and adapted to be controlled by an electrical trigger signal with a second, lower slew rate for operating the transceiver in receiver mode.
