Zusammenfassung:	Analog counter circuits, read-out integrated circuits, and infrared detector devices are disclosed. In one embodiment, an analog counter circuit includes a first capacitor including a first terminal and a second terminal, a switch electrically coupled the first capacitor and a first voltage input, a field effect transistor, and a second capacitor. Setting the switch to an on-state pre-charges the first capacitor such that a voltage at the second terminal of the first capacitor is the first voltage. Applying a charge voltage at a charge input further charges the first capacitor. When a voltage at the second terminal of the first capacitor is greater than a threshold voltage of the field effect transistor, the field effect transistor turns on and transfers a charge on the first capacitor to the second capacitor.
