What Are Comparators and Why Are They Used for?
About comparator Memory Components and Its Product Range:
A comparator is referred to in electronics as a device that compares two voltages or currents, indicating which is larger via a digital signal. These are usually composed of a high-gain differential amplifier and are used in such devices as analog-to digital converters (ADCs), relaxation oscillators, null detectors, level shifters, and other devices that measure analog signals. More specifically, there are such things as digital comparator (or magnitude comparator) and current comparator. Digital comparator are hardware electronic devices that input two numbers as binary, deciding which number is greater than, less than, or equal to another number. The main use of these is in central processing units and microcontrollers. These are more specific to our discussion as they are mainly utilized in computer hardware. In terms of key features and benefits of digital comparator, they perform magnitude comparison of binary words, have serial or parallel expansion without extra gating, have low power CMOS, and have CMOS and TTL input options. The analog equivalent would be the voltage comparator, which was discussed in brief detail above.
The mechanics behind a comparator itself is very basic, although the characteristics and specifications involved are somewhat more complicated. One must consider the speed and power, output type, hysteresis, and the internal reference, as well as whether it is continuous versus clocked.
One such major manufacturer of the discussed comparator is STMicroelectronics, which is a multinational electronics and semiconductor manufacturer based in Switzerland. They are actually the largest semiconductor chip maker in Europe and are one of the industry leaders in semiconductors, smartcard chips, automotive integrated circuits, and chips for a variety of other applications. In addition, they have a US headquarters in Texas an Asia headquarters in Singapore and Tokyo. Their revenue was $9.735 billion as of 2011 with total profit at $650 million and 49,450 employees. 72.4% of their stock is public on the New York Stock Exchange, Euro next Paris, or Borsa Italian Milano. STMicroelectronics offers many types of amplifiers and comparator, including the largest portfolio of micro-power op amps. They have also have state-of-the-art comparator. These include high-speed comparator and micro power comparator. Their high-speed comparator have response times that are as fast as 8 ns while their micro power comparator have operating currents as low as 210 NA.
