Comparators are classified into various types, such as electronic comparators, electrical, mechanical, optical, sigma, digital and pneumatic, these are used in various applications. Comparators play an essential role in the design of electrical and electronic projects. In electronic circuits, an op-amp is used with negative feedback and can also be used as a comparator. The comparator is primarily designed without feedback for the open loop configuration. These are widely used in A / D converters. When the i / p signal is sampled, then this sig ....etc

A Low-Voltage Low-Power Comparator With
Current-Controlled Dynamically-Biased
Preamplifiers For DCM Buck Regulators

Hoi Lee
Department of Electrical Engineering,
The University of Texas at Dallas,
Richardson, TX 75080-3021, USA.



Abstract-

Comparator-controlled power switch has been widely used to improve power efficiencies of discontinuous-conductionmode (DCM) buck regulators. Some major design challenges are capabilities of the comparator to operate at low voltage and dissipate low power for low-voltage DCM ....etc

CMOS COMPARATOR



Designing the Comparator with NMOS Input Drivers

Determine the first stage biasing current using the minimum allowable size of (W/L)=1, and minimum output offset.
(a) Consider M4 and M6.
Using the minimum size for M4, determine the current ISD4 that mirror with M6. That is,

The project is to shut down the power supply when it is overload. Conventional circuit breaker is based on thermal bimetal lever trip mechanism which is very slow and the trip time is dependant upon the percentage of overload. The voltage sensed is compared against the preset voltage proportional to the current by a level comparator to generate an output for the contactor to trip the load. ....etc

The Solex company was founded by Marcel Mennesson and Maurice Goudard to manufacture vehicle radiators. These were fitted to several makes of early cars including Delaunay-Belleville and buses of the Paris General Omnibus company.

After World War I, the radiator business went into decline and the company bought the rights to the carburetor patents of Jouffret and Ren e and named them Solex after their business.

The Solex brand is now owned by Magneti Marelli. The original Solex company changed its name in 1994 to Magneti Marelli France a ....etc

Pneumatic Comparators (Solex Gauge):
Principle:

It works on the principle of pressure difference generated by the air flow. Air is
supplied at constant pressure through the orifice and the air escapes in the form of jets
through a restricted space which exerts a back pressure. The variation in the back pressure is
then used to find the dimensions of a component.

Working:

As shown in Figure (a) the air is compressed in the compressor at high pressure which
is equal to Water head H. The excess air escapes in the form of bubbles.
Th ....etc
