CURRENT SUPPLY CIRCUIT UNRELATED PVT VARIATION AND SEMICONDUCTOR HAVING THE SAME

摘要

PURPOSE: A current supply circuit unrelated PVT variation and a semiconductor having the same are provided to generates a driving current in regardless of PVT change. CONSTITUTION: A reference voltage generator(20) generates a reference voltage. A current circuit generates a certain reference current. A current source(40) mirrors a base current and generates a mirror current. A base current is generated based on the reference voltage and is a replica current of a reference current.
