APPARATUSES AND METHODS FOR TEMPERATURE INDEPENDENT CURRENT GENERATIONS

摘要

Apparatuses and methods for providing a current independent of temperature are described. An example apparatus includes a current generator that includes two components that are configured to respond equally and opposite to changes in temperature. The responses of the two components may allow a current provided by the current generator to remain independent of temperature. One of the two components in the current generator may mirror a component included in a voltage source that is configured to provide a voltage to the current generator.

1. An apparatus, comprising:
a voltage generator configured to provide a voltage; and a current generator coupled to the voltage generator and configured to provide a current based on the voltage from the voltage generator, wherein the current generator includes a first component that has a property that increases as temperature increases and a second component that has the property that decreases as temperature increases; wherein the second component is configured to decrease the property at a rate equal to a rate the first component increases the property and wherein the second component matches a resistance of the voltage generator.
