Some ideal operational amplifier (often op-amp or opamp) configurations assume that the feedback resistors exhibit perfect matching. In practice, resistor nonidealities can affect various circuit ...

One of the biggest problems for designers of op-amp circuitry arises when the circuit must be operated from a single supply, rather than ± 15 V. This application note provides working circuit examples ...

Maybe you are familiar with the op-amp as an extremely versatile component, and you know how to quickly construct a huge variety of circuits with one. Maybe you even have a favorite op-amp or two for ...

b. The gain is set by VCC as the higher the supply voltage, the higher the gain. c. By the value of R3 as this resistor to ground sets the offset bias seen by the op-amp hence the gain. d. By the ...

Sponsored by Texas Instruments: Operational amplifiers serve many applications, from measuring current through a shunt to converting a photoconductive photodiode’s output to a voltage. The precision ...

As part of our Op-Amp Challenge we’re seeing a wide diversity of entries showcasing the seemingly endless capabilities of these extremely versatile parts. Another one comes from [Joseph Thomas], who ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...

Introduction to fundamental concepts and applications of electrical engineering. Topics include: circuit analysis from dc resistive networks to networks of impedances operating in the sinusoidal ...
