Abstract
A pixel includes a constant current source electrically connected to a first node. An integrating capacitor is electrically connected between the first node and a ground. A sampling transistor is electrically connected between the first node and a second node. A photodiode is electrically connected between a base terminal of the sampling transistor and the ground for switching electrical connectivity through the sampling transistor in response to radiation incident on the photodiode.
