Abstract
An electronic amplifier circuit according to the principle of current detection is coupled to a memory cell field and has an input transistor for each respective row or column of the matrix array. The input transistor is connected to the respective row or column and can be driven and switched by a control signal of a multiplexer circuit. The amplifier circuit may be constructed as a gate circuit or as a transistor diode circuit. A matrix array of memory cells and a matrix array of photodetectors are also provided.
