Abstract

The invention discloses an H-bridge switching circuit applied to epilepsy stimulation treatment. The H-bridge switching circuit comprises an H-bridge switch capable of selecting positive and negativestimulation electrodes and a corresponding switch control circuit. According to the circuit, time division multiplexing stimulation can be carried out on a plurality of electrodes through one stimulation current source, and the polarities of the electrodes are selected to realize proper stimulation waveforms; the switch adopts an LDMOS tube, and can be well compatible with a conventional low-voltage process.

Description

technical field [0001] The invention belongs to the technical field, and in particular relates to an H-bridge switch circuit applied to epilepsy stimulation treatment. Background technique [0002] The integrated circuit industry is the core of the information technology industry, and it is a strategic, basic and leading industry that supports economic and social development and guarantees national security. However, as some countries frequently impose chip embargoes on my country for various reasons, it has seriously hindered the development of my country's economy and national defense. At the same time, this also stimulated the process of domestic chip industrialization. With the introduction of the "National Integrated Circuit Industry Development Promotion Outline" in June 2014, it marked that my country's integrated circuit industry has risen to a national strategic level. [0003] With the rapid development of electronic technology, integrated circuits are increasingl...
