A CMOS rail-to-rail linear VI-converter [PDF]
Proceedings of ISCAS'95 - International Symposium on Circuits and Systems, 2002 A linear CMOS VI-converter operating in strong inversion with a common-mode input range from the negative to the positive supply rail is presented. The circuit consists of three linear VI-converters based on the difference of squares principle. Two of these perform the actual V to I conversion, while the third changes the bias currents of the first two

Study on the electrical resistance of the sleeper-fastening elements system in railway tracks
Materiales de Construccion, 2012 The electrical resistance of the sleeper-fastening elements system in a wet railway track is a very important parameter. This is because the rails are electric conductors in the circuit of signaling and traction systems.
