CALCULATION REGULATION FOR REDUCTION OF A MINORITY TREATMENT INTO A SUBSTREAT

摘要

A circuit configuration for reducing an injection of minority carriers into a substrate protects against malfunction due to injected minority carriers by providing a series circuit connected to an external terminal. The series circuit has a transistor and a diode disposed between a supply potential and the external terminal and fed back through a control loop from the external terminal to a control terminal of the transistor.
