CMOS inverter (a NOT logic gate). Complementary metal–oxide–semiconductor (CMOS, pronounced "sea-moss ", / s iː m ɑː s /, /-ɒ s /) is a type of metal–oxide–semiconductor field-effect transistor (MOSFET) fabrication process that uses complementary and symmetrical pairs of p-type and n-type MOSFETs for logic functions.

A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic ...
This USART has a 3-byte receive buffer and a 1-byte transmit buffer. It has hardware to accelerate the processing of HDLC and SDLC. The CMOS version (Z85C30) provides signals to allow a third party DMA controller to perform DMA transfers. It can do asynchronous, byte level synchronous, and bit level synchronous communications.

The benefits of full-custom design include reduced area (and therefore recurring component cost), performance improvements, and also the ability to integrate analog components and other pre-designed—and thus fully verified—components, such as microprocessor cores, that form a system on a chip.
In LEDs, transparent epoxy or a silicon caulk-like material that may contain a phosphor is poured into a mold containing the LED(s) and cured. The mold forms part of the package. COF: Chip-on-flex: Variation of COB, where a chip is mounted directly to a flex circuit. Unlike COB, it may not use wires nor be covered with epoxy, using underfill ...
In high performance CMOS (complementary metal–oxide–semiconductor) amplifier circuits, transistors are not only used to amplify the signal but are also used as active loads to achieve higher gain and output swing in comparison with resistive loads. [1] [2] [3] CMOS technology was introduced primarily for digital circuit design.
Asad Ali Abidi developed RF CMOS technology at UCLA during the late 1980s to early 1990s.. Pakistani engineer Asad Ali Abidi, while working at Bell Labs and then UCLA during the 1980s–1990s, pioneered radio research in metal–oxide–semiconductor (MOS) technology and made seminal contributions to radio architecture based on complementary MOS (CMOS) switched-capacitor (SC) technology.

Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining millions or billions of MOS transistors onto a single chip. VLSI began in the 1970s when MOS integrated circuit (metal oxide semiconductor) chips were developed and then widely adopted, enabling complex semiconductor and telecommunications technologies.
