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.

Abstract: A decoder for sequentially enabling outputs in response to clock signal inputs is described including X number of logic stages corresponding to X number of outputs of the decoder. Each of the logic stages has a plurality of inputs, wherein each logic stage includes fewer than log2X inputs for receiving the clock signal inputs.
