Claim Text:
1. An apparatus comprising: one or more cells each including a respective source follower transistor, wherein a first cell of the one or more cells includes a first source follower transistor; a detector module coupled to the one or more cells, the detector module including circuit logic to receive a first signal from the first cell and, in response to a pulse of the first signal, to indicate a detection of a first random telegraph noise event in the first source follower transistor; a counter module coupled to the detector module, the counter module including circuit logic to perform a first count update in response to the indicated detection of the first random telegraph noise event and, based on the first count update, to communicate a number corresponding to a plurality of random telegraph noise events; and control logic to transition the apparatus between a first mode and a second mode, the first mode for generating the number corresponding to the plurality of random telegraph noise events, wherein the second mode is for capturing an image with the one or more cells.
