We analog designers take great pains to make our amplifiers stable when we design them, but there are many situations that cause them to oscillate in the real world. Various types of loads can make ...

We uncovered an audio myth on our YouTube channel I didn’t even know was being perpetuated by some esoteric amplifier companies. Apparently there is a belief that designing an amplifier to be too ...

IC amplifiers are among the most basic building blocks in any designer’s tool box and represent one of the most versatile products available. An amp can provide a wide variety of functions such as ...

In 2008, Bob Pease exchanged e-mails with Linear Technology’s Mark Thoren, me, and a few other friends. The subject was how an amplifier will oscillate if you put a capacitive load on it. Bob knew ...

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 ...

Phase noise of quantum-enhanced feedback oscillators. Spectra of the output phase quadrature for four types of quantum noise-limited oscillators. Red shows the Schawlow-Townes spectrum of an ...

Current‐mode amplifiers have emerged as a highly efficient alternative to traditional voltage‐mode systems, particularly in high frequency and low power electronic applications. Their ability to ...
