Buck Converter · 2012

This application note describes how the NCP3063 can be configured as a buck controller to drive an external PFET transistor to produce a cost effective, high efficiency 3 A switching regulator. The NCP3063 has a wide input voltage range up to 40 V which makes it attractive for industrial and consumer applications such as LCD-TVs. The design example illustrates a buck converter delivering 3 A at 5 or 3.3 V from a 12 V supply. The block diagram of the NCP3063 controller is shown in Figure�1.

Blink Comparator

H. E. Lazerson · Archives of Ophthalmology · 1984

A newly designed blink comparator functions by presenting similar images that are alternated rapidly by varying the illumination. The device allows one to detect small changes easily without tedious measurements or study; it also serves as a stereo viewer.

LATCH COMPARATOR

Bertulessi Luca, Michele Rocco, Cristofoli Andrea · Virtual Community of Pathological Anatomy (University of Castilla La Mancha) · 2024

The invention consists in a single-stage FIA-based comparator with an embedded latch, which is insensitive to input common-mode voltage variations. With respect to the state-of-the-art FIA-based comparator architectures, the invention: a) has a simpler implementation, because of the single-stage topology, eliminating the interface between the pre-amp and the latch; b) does not require the design of additional logic gates to open the reservoir switches since the circuit already incorporates a self-quenching mechanism that automatically stops the reservoir capacitor discharge.

Magnetic Comparator

Sanford, Raymond L. (Raymond Laraway), b. 1884 · National Institute of Standards and Technology (NIST) · 1936

This device, devloped at the National Bureau of Standards around 1936 by Raymond L. Sanford, is an alternating-current bridge. The readings depend on the difference in the shape of the magnetic hysteresis loops of the test specimen and a reference specimen of known quality. This comparator was developed for the non-destructive testing of tool-resisting prison bars, but was used for various other valuable applications, such as the study of high-carbon drill steel. It was adapted to checking the heat treatment of drills during the manufacturing process.

Zeiss Comparator of the Allegheny Observatory. The "Spectrocomparator" was Designed in 1904 by the Company Carl Zeiss Jena, Founded by Noted Optician, Dr. Carl F. Zeiss. The "Stereocomparator" is an Instrument that Permits the Measurement of Relative Distances and Reveals Changes within a Star Field by Comparing One Image Against Another Simultaneously. This Tool Was Invaluable for the Discovery of Many Celestial Wonders Including Asteroids, Comets, and the Discovery of Pluto.

Comparator Approaches

Cento Veljanovski · Oxford University Press eBooks · 2020

Abstract This chapter explores the before and after and yardstick approaches, which use simple comparisons of prices and gross margins either over time or across markets, products, and/or regions. The most common method to estimate an overcharge is to use pre- and/or post-cartel prices as the non-cartel price, and to assume that the actual prices which exceed these prices during the cartel period represent the overcharge. This is known as the straight-line before-and-after price approach. The non-infringement price can be further adjusted during the cartel period by changes in costs and other fluctuations such as foreign exchange movements. The prices during price wars may also be used as a proxy for the non-infringement prices, but this requires an understanding of the causes of the price war to decide whether or not it affects the non-infringement prices. Where prices decline during the cartel period, the use of straight-line approaches is not appropriate. The yardstick approach is an alternative method, but requires that there be a comparator market with very similar characteristics to the cartel market so that the presence of the cartel is the only factor that explains its higher price.
