A Rail-to-Rail high speed continuous time comparator for ToF application

A 2V Rail-to-Rail Micropower CMOS Comparator

The design of a rail-to-rail micropower comparator in CMOS technology is described. The circuit is intended for implantable biomedical devices powered by batteries, with a total consumption of 500nA and operation up to supply voltages of 2V. This cell, currently being fabricated, has a core die area of 0.27 mm2 on a 2.4###m standard analog CMOS technology with a 0.85V nominal threshold voltage....

Low power/low voltage high speed CMOS differential track and latch comparator with rail-to-rail input

A new CMOS differential latched comparator suitable for low voltage, low-power application is presented. The circuit consists of a constant-gm rail-to-rail common-mode operational transconductance amplifier followed by a regenerative latch in a track and latch configuration to achieve a relatively constant delay. The use of a track and latch minimizes the total number of gain stages required fo...

Lessons for Policy Makers in Non-High Speed Rail Countries: A Review

High speed intercity passenger rail is an inherently strong railway application. It operates over 250 km/hour. For perspective, high-speed represents the ultimate development of preexisting standard gauge infrastructure. Network of high-speed passenger rail lines aimed at reducing accident, reducing traffic congestion, air pollution cutting national dependence on foreign oil and improving rural...
