Abstract
A sensor apparatus includes an array of active sensor elements arranged in columns and rows. Each sensor element is associated with a thin film access device disposed in a first current path through which an activation current is provided to activate the sensor element. Each sensor element is read through a respective second current path. The second current paths do not include the thin film access device of the first current path. As such, noise from the thin film access device is isolated from the second current paths.
