The invention relates to a proximity sensor arrangement () comprising a substrate (), a circuit board () carrying contact surfaces () which is mounted on a surface () of the substrate () and at least one support () which carries contact surfaces () complementary to the contact surfaces () of the circuit board () and at least one proximity sensor () with a measuring electrode () and a shield electrode () extending between measuring electrode () and surface (). In order to bring the contact surfaces () of the circuit board () and of the support () into contact, the substrate () and support () are plug-connected in a plugging direction (R, L) running parallel to the surface () of the substrate ().

Proximity sensor arrangement

A more efficient driver circuit for a power output stage, comprising a power driver stage activating the power output stage; a trigger circuit having an input stage and activating the power driver stage; and a power supply stage, wherein the input stage comprises a means for the potential-separated feeding of input signals, and the power supply stage comprises a means for the potential-separated feeding of electrical power. Such a driver circuit allows short signal propagation delays, is compact and small in size and has a wide clock frequency bandwidth.
