Constant-G/sub m/ rail-to-rail common-mode range input stage with minimum CMRR degradation
IEEE Journal of Solid-State Circuits, 1993The inherent drawbacks associated with CMOS amplifiers with rail-to-rail input common-mode range (CMR) are addressed. It is shown how they impact on the amplifier and limit its performance. An input stage, suitable to be incorporated in the design of any amplifier topology with extended input range, is introduced.

Current mode instrumentation amplifier with rail-to-rail input and output
Proceedings of the 20th annual conference on Integrated circuits and systems design, 2007A Current Mode Instrumentation Amplifier with rail-to-rail input and output is presented. It is based on constant gm input stages, and cascode output stages. Although this CMIA structure has a good Input Common Mode Voltage, it suffers from a poor output swing, due to the limitation imposed by the current mirrors.

Energy Requirements of the Rail Mode
Journal of Engineering for Industry, 1978The results of computer simulations of railroad operations to determine the energy required to pull freight and passenger trains over mountainous and flat profiles is presented. The effect of variations in average speed, profile and types of freight cars, is also determined.

Rail breaks caused by rolling contact fatigue defects are of growing concern to the railway industry. Very often critical defects cannot be detected reliably by conventional inspection methods. Low-frequency surface waves with a high penetration depth have the potential to overcome such difficulties.

Mode repulsion of ultrasonic guided waves in rails
Ultrasonics, 2018Accurate computation of dispersion characteristics of guided waves in rails is important during the development of inspection and monitoring systems. Wavenumber versus frequency curves computed by the semi-analytical finite element method exhibit mode repulsion and mode crossing which can be difficult to distinguish.

1V rail-to-rail constant Gm amplifier with common-mode elimination technique
2013 IEEE International Symposium on Circuits and Systems (ISCAS2013), 2013In this paper we present a novel common-mode elimination technique for a 1V rail-to-rail CMOS amplifier. For 1V single supply voltage, the input signal compression technique ([1]) is used to avoid the dead zone of input stage. Before the conventional PMOS input amplifier, the original signal is processed by the common mode elimination block which is ...

A 1.2 V rail-to-rail differential mode input linear CMOS transconductor
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003Rail-to-rail differential mode input capability in low voltage CMOS transconductor design is implemented by a pull-down and a pull-up follower in an input buffer. By generating three intermediate voltages in the buffer stage, three voltages are converted to three currents and subsequently summed using MOSFETs operating in the triode region.

ON THE EXISTENCE OF ZERO GROUP VELOCITY MODES IN RAILS
Proceedings of the 13th International Workshop on Structural Health Monitoring, 2022Ultrasonic guided waves are of practical interests for nondestructive evaluation (NDE) and structural health monitoring (SHM) since users can promote desirable wave modes for damage detection, thickness measurement, surface condition characterization, stress measurement, and so on.
