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.
