Title:
AMPLIFICATION CIRCUIT AND RECTIFYING ANTENNA
Document Type and Number:
WIPO Patent Application WO/2019/205629
Kind Code:
A1
Abstract:
An amplification circuit and a rectifying antenna. The amplification circuit comprises: a first rectifying circuit (20), which is configured to output a first direct current signal according to an alternating current signal; a second rectifying circuit (30), which is configured to output a second direct current signal according to an alternating current signal; and a differential amplification circuit (40), which is configured to receive the first direct current signal and the second direct current signal, and amplify and then output the difference value between the first direct current signal and the second direct current signal, the directions of the first direct current signal and the second direct current signal being opposite to each other. The present amplification circuit may improve the sensitivity of a rectifying antenna at a relatively low cost.
