31SEPIC converter — A SEPIC (single ended primary inductor converter) is a DC DC converter which allows the output voltage to be greater than, less than, or equal to the input voltage. The output voltage of the SEPIC is controlled by the duty cycle of the control… …
32Sample and hold — In electronics, a sample and hold circuit is used to interface real world signals, by changing analogue signals to a subsequent system such as an analog to digital converter. The purpose of this circuit is to hold the analogue value steady for a… …
332N7000 — The 2N7000 is a N channel, enhancement mode MOSFET used for small signal switching applications. Packaged in a TO92 enclosure, the 2N7000 is a 60 volt device capable of switching in the 200 350 milliamp range with an on resistance of 0.3 5 ohms.… …
34Matching — may refer to: Matching (graph theory), in graph theory, a set of edges without common vertices Matching (statistics), a technique for reducing bias when analyzing data from observational studies String matching, in computer science Matchmaking,… …
35Transistor models — Transistors are complicated devices. In order to ensure the reliable operation of circuits employing transistors, it is necessary to scientifically model the physical phenomena observed in their operation using transistor models. There exists a… …
36Hysteresivity — derives from “hysteresis”, meaning “lag”. It is the tendency to react slowly to an outside force, or to not return completely to its original state. Whereas the area within a hysteresis loop represents energy dissipated to heat and is an… …
37Pockels effect — The Pockels effect, or Pockels electro optic effect, produces birefringence in an optical medium induced by a constant or varying electric field. It is distinguished from the Kerr effect by the fact that the birefringence is proportional to the… …
38Power dividers and directional couplers — A 10 dB 1.7–2.2 GHz directional coupler. From left to right: input, coupled, isolated (terminated with a load), and transmitted port …
39Loudspeaker — For other uses, see Loudspeaker (disambiguation). An inexpensive, low fidelity 3½ inch speaker, typically found in small radios …
40Current source — Figure 1: An ideal current source, I, driving a resistor, R, and creating a voltage V A current source is an electrical or electronic device that delivers or absorbs electric current. A current source is the dual of a voltage source. The term… …
