Abstract

A reference circuit configured to provide a reference value. The circuit includes a first circuit unit which is configured to provide a first electrical representation that varies linearly with temperature and has a crossover point where its polarity relative to zero changes from a negative value to a positive value. A second circuit unit is configured to provide a second electrical representation that varies linearly with temperature. The first and second circuit units are operable for facilitating combining the first and second electrical representations such that the combination has a value corresponding to the value of the second electrical representation at a reference temperature.
