Schaltungsanordnung zur Bereitstellung einer Ladung basierend auf einem Eingangsstrom

DE1004042184 B UPAB: 20051130 NOVELTY - The circuit arrangement has an input (13) to receive an input current and an output (15) to provide a charge. It also has first and second charge storage elements. A first switch unit has a first switch state in which the first and second charge storage elements are charged in dependence on an input current. The first switch unit has a second switch state in which the first and second capacitors are decoupled from the current input and the first capacitor is decoupled from the second capacitor and the output. The arrangement also has a second switch unit with a first switch state in which the charge of the second capacitor is provided at the output, and a second switch stat in which the second capacitor is decoupled from the output. The second switch unit is in the second state when the first unit is in the first state; and the first unit is in the second state when the second unit is in the first state. USE - Especially for computer tomography and systems where sensor data is processed into digital signals. ADVANTAGE - Has low current and large dynamic range
