Abstract
A new circuit for microbolometer bias-heating cancellation is described. Th e circuit is based on the equivalence between the electrical and thermal ca pacitance. A replica of the bias-heating effect is generated on the electri cal capacitance and is used to effectively cancel the bias heating of the m icrobolometer. The cancellation is tunable.
