Abstract: An image capturing device is provided, which includes a capacitive trans-impedance amplifier (CTIA) unit cell. The CTIA unit cell includes an image detector and a switching network. The image detector is configured to detect light having a first color and light having a second color different from the first color, and to generate a photocurrent in response to detecting the light. The switching network includes a CTIA switch, a CTIA low reset switch, and a CTIA high-reset biasing switch. The CTIA switch sets a first reset level of the CTIA unit cell to a first voltage in response invoking a first switching state of the CTIA low-reset switch and sets a second reset level of the CTIA to a second voltage greater than the first voltage level in response to invoking a second switching state of the CTIA low-reset switch.

Abstract: According to one embodiment, a circuit comprises a Capacitive Trans-Impedance Amplifier (CTIA) configured to receive a current pulse at an input and convert the current pulse to a voltage step. The voltage step is directed to a first signal path and a second signal path. When the voltage step exceeds a first threshold, the first signal path directs an enable pulse to the second signal path. The second signal path generates an output pulse when the voltage step exceeds a second threshold and the enable pulse is enabled. The second signal path comprises a first, a second, and a third amplifier to increase detection of the voltage step by the second signal path.
