摘要： A low power (optionally, self-powered) integrated transceiver using on-chip antennas is provided. The transmitter and receiver utilize phase-locked loops (PLLs) which initially, in a closed-loop state, pre-tune (i.e. phase-lock) voltage controlled oscillators (VCOs) before opening the loops to allow them to transmit and receive data. The TX, in the opened-loop state, disables the loop components while (FM) modulating the VCO. The RX, in the opened-loop state, injection-locks the VCO with the incoming (FM) modulated signal while the remaining loop components serve to demodulate the signal. For both the TX and RX an integrated antenna can be used and, advantageously, the TX comprises a dual purpose inductor which functions as both an inductor in the voltage-controlled oscillator (i.e. in the resonant tank thereof) and the integrated antenna.
