Abstract
An anti-logarithmic type converter circuit, with temperature compensation, includes a diode connected between a unity gain, non-inverting interface circuit and a low-impedance reference voltage circuit. A thermal compensation circuit is connected between the converter input and the interface circuit. The thermal compensation circuit includes current mirror circuits having a gain higher than one and their output currents linearly dependent on temperature.
