Current sensor with the semiconductor measuring element, preferably in the application for inbuilding into an integrated circuit

摘要

the subject invention is a power, in which the main current flows through the transistor in the circuit being measured. to measure using current base transistor (1) proportional to the current flowing through the transistor in such a way that, in a similar symmetric system, built on an identical tranzystorze is caused repeatedly less electricity.the current collector transistor circuit is many times smaller than the symmetrical current collector transistor measuring how many times the value in the base of a transistor rezystora is symmetrical from rezystora base transistor in circuit measurement.
