Title:
AMPLIFICATION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2021/102656
Kind Code:
A1
Abstract:
An amplification circuit comprises an amplifier (11) and a current follower (12). An input terminal of the current follower (12) serves as an input terminal of the amplification circuit, an output terminal of the current follower (12) is connected to an input terminal of the amplifier (11), and an output terminal of the amplifier (11) serves as an output terminal of the amplification circuit. The structure reduces the impact of equivalent ground capacitance on the SNR.
