Abstract
A HDR CTIA pixel which provides automatic gain selection, and spatial and temporal coherence. The pixel comprises an input node for connection to a photocurrent, and an output node. The pixel includes a CTIA which comprises a 'high gain' integration capacitor and a first reset switch connected between the input and output nodes, a 'low gain' integration capacitor connected between the input node and a first node, a second reset switch connected between the first node and the output node, and a first FET connected across the second reset switch. In operation, the first FET is off during the reset phase, and is conditionally turned on during or after the integration phase. The CTIA also includes an amplifier having an inverting input connected to the input node and an output connected to the output node. The pixel can be operated in “static low-gain control” and “dynamic low-gain control” modes.
