sensing circuit in the form of a threshold value haen independently of the field effect transistor - flip - flip-flop

摘要

An f.e.t. flip flop sensor is designed to be threshold-independent. The threshold differences between the two branches are eliminated. A first and second transistor are connected in series to each of the two flip-flop transistors. The cross-coupling between the connecting point of the first and second transistor of the one branch runs with the gate electrode of the flip-flop transistor of the other branch. The flip-flop (10) has six active switching elements (12, 14, 16, 18, 20, 22) which consist of metal oxide semiconductor field-effect transistors. The flip-flop (10) is connected to a number of storage cells.
