Abstract

The embodiment of the invention provides an electric leakage protection circuit, an integrated circuit, an electronic device and a method. The electric leakage protection circuit comprises an electricleakage detection circuit, a compensation trigger circuit and an electric leakage compensation circuit, and the electric leakage detection circuit comprises a detection capacitor and is used for being connected with a to-be-detected circuit and charging the detection capacitor through the electric leakage current of the to-be-detected circuit; the compensation trigger circuit is connected to theelectric leakage detection circuit and is used for detecting the magnitude of electric leakage current during the charging of the detection capacitor and outputting a trigger signal when the electricleakage current is greater than or equal to a preset threshold value; the electric leakage compensation circuit is connected to the compensation trigger circuit and is used for providing compensationcurrent corresponding to the electric leakage current for the to-be-detected circuit according to the trigger signal. The electric leakage protection circuit provided by the embodiment of the invention can effectively eliminate the influence of system electric leakage and improve the detection range and precision of signals.

Description

technical field [0001] The present application relates to the technical field of electronic circuits, in particular to a leakage protection circuit, an integrated circuit, electronic equipment and a method. Background technique [0002] The Internet of Things (IoT) is a highly integrated and comprehensive application of a new generation of information technology. The architecture of the Internet of Things is divided into perception layer, network layer and application layer. Among them, the sensing layer of the Internet of Things is composed of sensors and gateways, which obtain information through sensors and control instructions through gateways. [0003] As the most basic link in the Internet of Things, sensors can regulate (such as acquisition, amplification, offset compensation, temperature compensation, linear compensation, etc.) various weak signals (such as pressure signals, gas signals, etc.). However, in the process of small signal processing, any leakage in the ...
