Abstract
A temperature compensation circuit converts a control signal (I ) that has an undesirable temperature coefficient to a temperature compensated control signal (I ) having a desirable temperature coefficient. In one embodiment, four transistors ( , and ) are configured to convert the control signal (I ) having an undesirable temperature coefficient to the temperature compensated control signal (I ) having the desired temperature coefficient. Additional embodiments use components to refine the temperature compensation process.
