Title:
TEMPERATURE DEPENDENCY CURRENT GENERATOR
Document Type and Number:
Japanese Patent JPS5755427
Kind Code:
A
Abstract:
A circuit for generating temperature dependent current for compensating an electrical circuit comprises a resistor and a semiconductor junction having different temperature coefficients. A current applied to the semiconductor junction conditions it for conduction and related potentials are maintained across the resistor and the semiconductor junction. Means receiving a portion of the current in one of the resistor and semiconductor junction develops the temperature dependent current in response to the portion. The temperature dependent current is applied to the electrical circuit to effect the desired compensation. One embodiment of the present invention includes a band-gap reference potential generating circuit in which a semiconductor junction thereof receives the temperature dependent current. Other embodiments of the present invention are employed to develop currents that are dependent upon a temperature function raised to a power.
