31Colpitts oscillator — Early schematic of a Colpitts circuit, using a vacuum tube, redrawn from the patent publication. A Colpitts oscillator, invented in 1920 by American engineer Edwin H. Colpitts, is one of a number of designs for electron …
32Telecommunications Engineer — Telecommunications Engineers or Telecom Engineers come in a variety of different types from basic circuit designers to strategic mass developments. A Telecom Engineer is responsible for designing and overseeing the installation of… …
33Cathode bias — In order for a vacuum tube (or valve) to operate in a fairly linear region of its characteristic curve, the grid element must be maintained at a bias voltage more negative than the cathode. This is called cathode bias.Early techniquesEarly… …
34Nanopolymers — The word nano is derived from the Greek word for “dwarf”. It is the prefix for units of 10 9. In a nutshell, nanoscience is the study of the extremely tiny. Nanoscience is concerned with the study of the unique properties of matter at its nano… …
35semiconductor device — ▪ electronics Introduction electronic circuit component made from a material that is neither a good conductor nor a good insulator (hence semiconductor). Such devices have found wide applications because of their compactness, reliability,… …
36Telecommunications engineering — Telecommunications engineering, or telecom engineering, is a major field within electronic engineering. The work ranges from basic circuit design to strategic mass developments. A telecommunication engineer is responsible for designing and… …
37Multivibrator — A multivibrator is an electronic circuit used to implement a variety of simple two state systems such as oscillators, timers and flip flops. It is characterized by two amplifying devices (transistors, electron tubes or other devices) cross… …
38Printed circuit board — Part of a 1983 Sinclair ZX Spectrum computer board; a populated PCB, showing the conductive traces, vias (the through hole paths to the other surface), and some mounted electrical components A printed circuit board, or PCB, is used to… …
39Common base — Figure 1: Basic NPN common base circuit (neglecting biasing details). In electronics, a common base (also known as grounded base) amplifier is one of three basic single stage bipolar junction transistor (BJT) amplifier topologies, typically used… …
