    Abstract: A coupling circuit comprising N stages connected in parallel between two conductors. Each stage comprises the conduction paths, in series, of two field effect transistors and an output terminal at the connection of the two paths. The output terminals are connected to the respective rows of an array of light sensing circuits. One transistor of one stage is turned on to connect one row of circuits through one conductor to an output circuit to permit the circuits of that row to be read out, in sequence. Concurrently, the other transistor of the following stage is turned on to connect the following row of circuits through the second conductor to ground to permit the circuits of the following row to be precharged. The process is continued until all rows of the matrix are successively precharged and read out.
