Abstract

An apparatus comprising a first circuit, a second circuit and a third circuit. The first circuit may be configured to generate a first current in response to a reference voltage. The first current may vary as a function of temperature. The second circuit may be configured to generate a second current to counteract for the variations of the first current. The second current may vary as a function of temperature. The third circuit may be configured to generate a third current in response to the first current and the second current.
