  • OP Amps deliberately straddles that imaginary line between the technician and engineering worlds. Topics are carefully addressed on three levels: operational overview, numerical analysis, and design procedures. Troubleshooting techniques are presented that rely on the application of fundamental electronics principles. Systematic methods are shown that can be used to diagnose defects in many kinds of circuits that employ operational amplifiers. One of the book's greatest strengths is the easy-to-read conversational writing style.

  • This third volume of the book series Lessons In Electric Circuits makes a departure from the former two in that the transition between electric circuits and electronic circuits is formally crossed. Electric circuits are connections of conductive wires and other devices whereby the uniform ow of electrons occurs. Electronic circuits add a new dimension to electric circuits in that some means of control is exerted over the ow of electrons by another electrical signal, either a voltage or a current....

  • Conventional servo systems, to ensure machine performance, smoothness, positional error and low servo noise, require the adjustment of its servo’s gains as an initial crucial step. Even systems that employ auto-tuning require manual tweaking after the system is installed, especially if more that one axis are interdependent. Ezi-SERVO® employs the best characteristics of stepper and closed loop motion controls and algorithms to eliminate the need of tedious gain tuning required for conventional closed loop servo systems.

  • The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes....

  • In this chapter, MATLAB will be used to solve problems involving metaloxide semiconductor field effect and bipolar junction transistors. The general topics to be discussed in this chapter are dc model of BJT and MOSFET, biasing of discrete and integrated circuits, and frequency response of amplifiers. 12.1 BIPOLAR JUNCTION TRANSISTORS Bipolar junction transistor (BJT) consists of two pn junctions connected backto-back. The operation of the BJT depends on the flow of both majority and minority carriers. There are two types of BJT: npn and pnp transistors.
