The compensator circuit is operative to change a voltage received at its input in accordance with the transfer function and to provide the changed voltage at its output. The additive component is preferably an Iodine compound that either absorbs heat during decomposition such as Iodine Pentoxide or an Iodine compound that absorbs heat during sublimation such as solid Iodine.
