<p>A switching circuit for precision switching of direct current signals. It is used for multi-stage switching of electrical signals where the residual voltage on the active switching modules are reduced. The active switching module is designed as an operational amplifier with negative feedback switching elements. There are two switching modules in series, and two similar storage circuits (3, 4) for the quiescent points of the operational amplifier (1, 2). The storage circuits are cross connected between the non-inverting inputs of the amplifiers (13, 14) and the outputs (11, 12) of the operational amplifiers.</p> |
