Claim:
1. An integrated circuit chip comprising: a temperature-sensitive element comprising a device having a temperature-dependent performance attribute; a first circuit in a region immediately adjacent to said temperature-sensitive element; and, a second circuit in said region, said first circuit being a functional circuit of said integrated circuit chip and said second circuit being a temperature-stabilization circuit of said integrated circuit chip, said first circuit and said second circuit being thermally coupled to said temperature-sensitive element, said second circuit sensing changes in a first current amount in said first circuit, said first circuit radiating a first heat amount to said temperature-sensitive element and said first heat amount varying with variations in said first current amount, said second circuit further automatically adjusting a second current amount in said second circuit in response to said changes, said second circuit radiating a second heat amount to said temperature-sensitive element and said second heat amount varying with variations in said second current amount, said second circuit performing said adjusting of said second current amount to ensure that a total heat amount radiated by said first circuit and said second circuit to said temperature-sensitive element remains constant.
