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 ...
The circuit was designed based on the functionality of an op-amp to create a Wien bridge oscillator to generate sine waves in the frequency range of 15 Hz to 150 kHz that is channeled using four ...
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 ...
1. Is Amplifier Weight an Indicator of Robust Amplifier Design? You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before you can generalize about weight ...
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 ...
