Abstract
A capacitive trans-impedance amplifier (CTIA) unit cell includes a CTIA and a clamp capacitor. The CTIA is configured to process a first electrical charge induced by a photocurrent. The clamp capacitor includes a first clamp terminal configured to receive a dynamic signal and a second clamp terminal connected to a CTIA output of the CTIA so as to establish an integrating node. The clamp capacitor delivers a second electrical charge to the CTIA in response to receiving the dynamic signal so as to adjust an integrating reset level at the integrating node.
