Abstract
A method for detecting infrared radiation by using an array of bolometers. The following steps are used to read a bolometer of the array of bolometers: biasing the bolometer at a predetermined voltage in order to make current flow through the bolometer; subtracting a common-mode current from the current that flows through the bolometers; and producing a voltage by integrating the difference between the current that flows through the bolometers and the common-mode current.
