Understanding SAR ADCs: Their Architecture and Comparison with Other ADCs. Abstract: Successive-approximation-register (SAR) analog-to-digital converters (ADCs) represent the majority of the ADC market for medium- to high-resolution ADCs.
SAR ADCs provide up to 5Msps sampling rates with resolutions from 8 to 18 bits. The SAR architecture allows for high-performance, low-power ADCs to be packaged in small form factors for today's demanding applications. This paper will explain how the SAR ADC operates by using a binary search algorithm to converge on the input signal.
It also explains the heart of the SAR ADC, the capacitive DAC, and the high-speed comparator. Finally, the article will contrast the SAR architecture with pipeline, flash, and sigma-delta ADCs.

A greatly simplified block diagram of the 80186 architecture.
The Intel 80186 (also known as iAPX 186)[1] is a microprocessor and microcontroller introduced in 1982. It was based on the Intel 8086 and, like it, had a 16-bit external data bus multiplexed with a 20-bit address bus. It was also available as the 80188, with an 8-bit external data bus. Description[edit] Features and performance[edit] The 80186 series was generally intended for embedded systems, as microcontrollers with external memory.
The initial clock rate of the 80186 was 6 MHz, but due to more hardware available for the microcode to use, especially for address calculation, many individual instructions ran faster than on an 8086 at the same clock frequency. The (redesigned) CMOS version, 80C186, introduced DRAM refresh, a power-save mode, and a direct interface to the 8087 or 80187 floating point numeric coprocessor. Uses[edit] In personal computers[edit] Other devices[edit] See also[edit] iAPX, for the iAPX name. Embedded Intel Architecture - Intel® 186 processors. Infrared radiation blackbody, radiation sources & infrared detector preamplifiers. Black body. As the temperature of a black body decreases, its intensity also decreases and its peak moves to longer wavelengths.
Shown for comparison is the classical Rayleigh–Jeans law and its ultraviolet catastrophe. A black body is an idealized physical body that absorbs all incident electromagnetic radiation, regardless of frequency or angle of incidence. A black body in thermal equilibrium (that is, at a constant temperature) emits electromagnetic radiation called black-body radiation. The radiation is emitted according to Planck's law, meaning that it has a spectrum that is determined by the temperature alone (see figure at right), not by the body's shape or composition. A black body in thermal equilibrium has two notable properties:[1] It is an ideal emitter: it emits as much or more energy at every frequency than any other body at the same temperature.It is a diffuse emitter: the energy is radiated isotropically, independent of direction.
Definition[edit] Process Controller, Series F4 Temperature Process Controls. The SERIES F4 1⁄4 DIN temperature process controller offers performance features to meet a wide range of industrial processing needs.
The F4 process controller is ideal for semiconductor manufacturing equipment, plastic processing and packaging equipment and industrial process control applications. This process controller features a four line, high definition LCD interface display, in addition to an information key that enables easy set up and control operation, minimizing the chance for error. Its 16-bit microprocessor ensures accuracy and delivers performance advantages you can count on from a Watlow controller. Four digital inputs remotely modify controller operation or enable display of pre-defined operator messages. Advanced process controller features include cascade, ratio, differential, duplex slide wire and retransmit options.
Specifications: Note: The specifications in the table above are best available values in each category. Features & Benefits: Images: PID controller. Some applications may require using only one or two actions to provide the appropriate system control.
This is achieved by setting the other parameters to zero. A PID controller will be called a PI, PD, P or I controller in the absence of the respective control actions. PI controllers are fairly common, since derivative action is sensitive to measurement noise, whereas the absence of an integral term may prevent the system from reaching its target value due to the control action. History and applications[edit] PID theory developed by observing the action of helmsmen. The Navy ultimately did not adopt the system, due to resistance by personnel. Electronic analog controllers can be made from a solid-state or tube amplifier, a capacitor and a resistor.
Most modern PID controllers in industry are implemented in programmable logic controllers (PLCs) or as a panel-mounted digital controller. Control loop basics[edit]
