Abstract
A temperature control circuit for an inkjet printhead including a temperature sensor portion that generates an output current made up of the sum of a current proportional to a sensed temperature on the inkjet printhead and an offset current, and an offset current correction portion that generates a correction current that is subtracted from the output current to at least partially compensate for the offset current, the output current as compensated by the correction current being output as a temperature control circuit output current.
