Tunable rail-to-rail FGMOS transconductor
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010A tunable CMOS transconductor is presented. Input rail-to-rail operation is achieved using floating-gate MOS (FGMOS) transistors. Tuning is also obtained using FGMOS transistors, which are biased in weak or moderate inversion to achieve precise output current scaling.

Measurement of rail current distribution in rail launchers
2014 IEEE International Instrumentation and Measurement Technology Conference (I2MTC) Proceedings, 2014This paper deals with the measurement of current distribution across the rails of rail launchers. The proposed approach is based on inductive method by magnetically coupling an array of search loops with the rail-armature circuit. The procedure was already successfully employed for current distribution measurements among the brushes of multi-brush ...

A 1.2 V rail-to-rail switched buffer
1998 IEEE International Conference on Electronics, Circuits and Systems. Surfing the Waves of Science and Technology (Cat. No.98EX196), 2002A CMOS low-voltage (1.2 V) switched buffer to be used as input stage in switched-opamp circuits is presented. The circuit is based on the use of an op-amp featuring rail-to-rail input and output swing with constant transconductance (gm) over the input common mode voltage. The circuit operates from a single 1.2 V, consuming about 0.6 mW.

Rail safety and rail privatisation in Japan
Accident Analysis & Prevention, 2010Over the period from 1980 to the present, the economic status of the main line railway systems in many developed countries has changed, by privatisation or economic deregulation or both. The principal aims of such changes have been to improve the economic performance of the railways, and not to change the safety performance.

The main goal of this work was to design an input stage which works rail-to-rail and have constant transconductance for the entire common mode range, and it was to be done without the necessity of matching p-and n-channel transistors. Two new circuits which possess these requirements were developed in the previous chapter; however, the effort will be ...

A CMOS op amp (operational amplifier) is reported which has a rail-to-rail voltage range at its input as well as its output. An area-efficient output stage has been used. While the entire op amp occupies only 600 mil/sup 2/, when used as a unity-gain buffer and with +or-5-V supplies, the op amp can drive a 9-V/sub pp//1-kHz sine wave across a 300 ...

Rail safety and rail privatisation in Britain
Accident Analysis & Prevention, 2007British Rail (BR), the former unified main line railway operator in Great Britain, was divided into about 100 separate organisations and privatised from April 1994. There was concern in the run-up to privatisation that the fragmentation of the system and the entry of new operators might compromise safety.
