emitter-coupled structure
1Hyperfine structure — In atomic physics, hyperfine coupling is the weak magnetic interaction between electrons and nuclei. Hyperfine coupling causes the hyperfine splitting of atomic or molecular energy levels. The totality of energy levels spawned by hyperfine… …
2Operational amplifier — A Signetics μa741 operational amplifier, one of the most successful op amps. An operational amplifier ( op amp ) is a DC coupled high gain electronic voltage amplifier with a differential input and, usually, a single ended output.[1] An op amp… …
3Avalanche transistor — An Avalanche Transistor is a bipolar junction transistor designed for operation in the region of its collector current/collector to emitter voltage characteristics beyond the collector to emitter breakdown voltage, called avalanche breakdown… …
4Transistor–transistor logic — (TTL) is a class of digital circuits built from bipolar junction transistors (BJT), and resistors. It is called transistor–transistor logic because both the logic gating function (e.g., AND) and the amplifying function are performed by… …
5Domino logic — is a CMOS based evolution of the dynamic logic techniques which were based on either PMOS or NMOS transistors. It allows a rail to rail logic swing. It was developed to speed up circuits. In Dynamic Logic, a problem arises when cascading one gate …
6Digital electronics — Main articles: Electronics and Electronic circuit Digital electronics represent signals by discrete bands of analog levels, rather than by a continuous range. All levels within a band represent the same signal state. Relatively small changes to… …
7Phase-locked loop — PLL redirects here. For other uses, see PLL (disambiguation). A phase locked loop or phase lock loop (PLL) is a control system that generates an output signal whose phase is related to the phase of an input reference signal. It is an electronic… …
8CMOS — For other uses, see CMOS (disambiguation). CMOS inverter (NOT logic gate) Complementary metal–oxide–semiconductor (CMOS) (   …
9Antenna (radio) — Whip antenna on car …
10Earth Sciences — ▪ 2009 Introduction Geology and Geochemistry The theme of the 33rd International Geological Congress, which was held in Norway in August 2008, was “Earth System Science: Foundation for Sustainable Development.” It was attended by nearly… …
