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), 2003
Rail-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.

Experimental studies of high-speed grinding rails modes

Metal Working and Material Science, 2023
Introduction. Rails’ grinding in the conditions of a railway track is a priority for extending its life cycle due to the timely removal of tread surface defects and formation of required transverse profile. Today, 14 RSHP-48 rail grinding trains are used in Russia. At the same time, most rail grinding trains are ending its service life.

Low-voltage linear OTA with rail-to-rail differential mode input signal capability

ICECS'99. Proceedings of ICECS '99. 6th IEEE International Conference on Electronics, Circuits and Systems (Cat. No.99EX357), 2003
A low-voltage linear operational transconductance amplifier (OTA) with rail-to-rail differential mode input signal capability is designed and fabricated by 0.8 /spl mu/m CMOS technology. The circuit is capable of operating at supply voltage larger than two times the MOS transistor threshold voltage V/sub T/.

Low-voltage CMOS GM-C filter with rail-to-rail common-mode voltage

Proceedings of the 39th Midwest Symposium on Circuits and Systems, 2002
In this paper, a CMOS design of low-voltage 5th-order elliptic low-pass GM-C filter with rail-to-rail common-mode input voltage is introduced. The Operational Transconductance Amplifier (OTA) inside this filter is a low-voltage rail-to-rail voltage-to-current converter (V-I converter). In this V-I converter, an N-type V-I converter cell is connected in

Input/Output Rail-to-Rail CMOS Operational Amplifier with Shaped Common-Mode Response

Analog Integrated Circuits and Signal Processing, 2003
This paper presents an input/output rail-to-rail class-AB CMOS operational amplifier with reduced variations in unity-gain frequency over the entire voltage range. The rail-to-rail amplifier input stage is based on two parallel-connected complementary differential pairs.

Peculiarities of Process Conditions and Rail Grinding Modes

2021
The scientific article analyzes the known materials used for the manufacture of railway rails and the problems encountered in their operation. As a result of rolling stock wheels acting on rails, various defects occur on them. Grinding technology is used to eliminate them.

A 1-V BiCMOS rail-to-rail amplifier with n-channel depletion mode input stage

IEEE Journal of Solid-State Circuits, 1997
A BiCMOS rail-to-rail operational amplifier capable of operating from supply voltages as low as 1 V is presented. The folded cascode input stage uses an nMOS depletion mode differential pair to provide rail-to-rail common mode voltage range while typically requiring only 40 fA of input bias current.

Mode II fatigue failures at rail butt-welds

Engineering Failure Analysis, 2005
Abstract Some typical fatigue failures of butt-welded rails consist of fractures of the web. In the early stage, the crack propagates parallel to the rail surface but, after a while, it tends to propagate with a slant surface. The aim of the present work is to analyse the mechanisms involved in crack propagation in rail webs and the crack path, which

Fully differential ADC with rail-to-rail common-mode range and nonlinear capacitor compensation

IEEE Journal of Solid-State Circuits, 1990
One of the sources of nonlinearity in charge redistribution analog-to-digital converters (ADCs) is capacitor voltage dependence. While it is possible to address this problem through capacitor fabrication technology improvements, situations arise where it is more desirable to use circuit techniques.
