摘要： An active transmission architecture without battery and the application are proposed, which make use of an analog front-end circuit to convert a received carrier into a dc signal for providing power for the active transmission architecture without battery, and therefore actively produces a replying signal with the same or different frequencies from the carrier. It is not necessary to add an extra power circuit, hence accomplishing the advantage of no battery. The proposed active transmission architecture without battery can apply to RFID systems or be used in applications that require transmitter and receiver modules.

摘要： A wireless short range transmission system comprises a controller, a first oscillator, a transmitter, and an antenna. The transmitter comprises a phase-lock loop frequency synthesizer for receiving a reference signal from the first oscillator and a first modulation signal. The phase-lock loop frequency synthesizer is configured to be turned on by the first modulation signal for generating a carrier signal based on the reference signal. The transmitter further comprises a power amplifier for receiving the carrier signal from the phase-lock loop frequency synthesizer and a second modulation signal. The power amplifier is configured to be turned on/off by the second modulation signal to generate a modulated signal based on the carrier signal. The power amplifier is turned on after the phase-lock loop frequency synthesizer is stabilized and the phase-lock loop frequency synthesizer is turned off with the power amplifier or after the power amplifier has been turned off.
