Abstract

The present invention relates to a voltage converter and a radio frequency identification device integrating such a voltage converter. The voltage converter includes: a first boost unit configured to generate a first boost signal at a first output based on the received input signal under the influence of the first clock signal and the second clock signal, and A second boost signal is generated at the second output terminal; a second boost unit is configured to generate a second boost signal based on the first boost signal and the second boost signal under the influence of the first clock signal and the second clock signal The third boost signal and the fourth boost signal. The voltage converter further includes an output unit configured to generate an output signal based on the third boost signal and the fourth boost signal. Through the technical scheme of the present invention, the threshold voltage loss and on-resistance on the voltage converter can be reduced, and the output voltage and driving capability of the voltage converter can be improved.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a DC voltage conversion circuit and a corresponding RFID tag. Background technique [0002] In recent years, radio frequency identification (Radio Frequency Identification, RFID) technology is more and more widely used in the Internet of Things (Internet of Things, IoT). A complete RFID system generally includes an RFID tag and a reader. The RFID tag is the data carrier. Its inductive sensitivity affects the RFID reading and writing distance, and its cost affects whether the RFID technology can be applied on a larger scale. Traditional RFID tags are implemented using monocrystalline silicon technology, but its high manufacturing cost limits the commercial application of RFID technology. For a long time, how to reduce the cost of RFID tags has been a key issue to be solved in the development of RFID technology. Contents of the invention [0003] One aspect of the present inv...
