Top 10 Fundamental Operational Amplifiers Circuits
As well as resistors and capacitors that are passive components, operational amplifiers are one of the basic building blocks of analogue electronic circuits. Operational amplifiers are linear devices that have all the properties required for nearly ideal DC amplification and are therefore used extensively in signal conditioning or filtering or to perform mathematical operations such as adding, subtracting, integration, and differentiation. The purpose of this article is to present 10 basics circuits for newcomers to electronics designs and to refresh the rusty minds of engineers.
Filter Out Unwanted Electrical Noise with Capacitors
Filtering is a fundamental part of many circuits and has wide-ranging applications, including audio processing, radio reception, and power circuit conditioning. A basic understanding of capacitors as a filtering component begins with understanding the types of filters and what they do.
What is Low-Side Current Sensing?
In this article, brought to you from Dan Harmon, Current Sensing Marketing Manager with Texas Instruments, Dan takes a look at low-side current sensing, talking about some of the fundamentals of current sensing, and talks specifically about the INA199 from Texas Instruments.
ADC Requirements for RTD Temperature Measurement Systems
There are several types of temperature sensors which can be used in a temperature measurement and control systems. The correct temperature sensor to use depends on the temperature range being measured and the accuracy required. Along with the sensor, the accuracy of the temperature system depends on the performance of the Analog-to-Digital Converter (ADC) to which the sensor is interfaced.
Using a Simple Diode as a Temperature Sensor
There are numerous devices on the market that read and monitor temperature. From simple thermometers to black body radiation optical measurements, many clever designers have invented techniques ranging from simple and intuitive, to complex and obscure. We're going to cover a common and simple technique of measuring temperature using standard low-cost diodes.
What is Direct Digital Synthesis?
Complete Direct Digital Synthesis (DDS) is a technique for producing an analog waveform by manipulating a fixed system clock digitally then running the output through a DAC. This allows for fine frequency resolution over a wide range of frequencies and quick switching between those frequencies.
Designing Cellular Technology into Embedded Systems
The market opportunity for connecting smart devices and machines with cellular connection is exploding. Even with all the innovation that has happened in the past couple of years, surprisingly, Machine to Machine (M2M) still only accounts for 2% of the overall cellular connections.
