Op Amps are among the most widely used components in systems design of electronic circuits. Although functionally simple, they exhibit complex behavior as the Op Amp itself is a carefully crafted ...

Operational amplifiers (op amps) play many different roles in optimizing the performance of mixed signal system design. Today’s mixed signal designer is challenged to understand the requirements of ...

Fig 1. This modified Wien-Bridge oscillator has three output states—high, low, and oscillation—that depend on the input voltage. It drives a bi-color LED to provide a visual indication of the input’s ...

A new class of precision amplifier, the LT1970, features a voltage-programmable output current limit with guaranteed 2% accuracy. While more rigid designs require a resistor to set the output current ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

You can take an op amp with rare input characteristics and elevate it to achieve higher voltage range, better gain accuracy, higher slew rate, and less distortion than the original op amp. I was ...

There are a number of reasons why an engineer would want to “split” a voltage rail in their design. Sometimes parts of the circuit, like a sensor or an IC, require a bipolar supply. Other reasons are ...

This white paper discusses a method for driving high-frequency sinusoidal ripple over capacitive loads for power supply rejection ratio (PSRR) testing, an important performance parameter for many ...

Of digital electronics, a wise man once said that “Every idiot can count to one.” Truer words have rarely been spoken, because at the end of the day, every digital circuit is really just an analog ...
