26-12-2023 | Here is an update to a 555 Class D Power Amplifier project first presented about a decade ago. Read on to learn about some of the improvemen...

20-06-2023 | The amplifier proposed here is a bit special as the output signal is not a voltage but a current. Therefore, the frequency dependence of the...

11-08-2020 | An audio amplifier can be part of the electronics lab too. This design for an audio test amplifier features three channels that can be used...

3-04-2018 | The current surge demanded at power-on by a circuit presenting a large capacitive load to the power supply can destroy the power supply or t...

15-08-2017 | So you’re back from holidays spent somewhere in a hot and sunny place, enjoying the a hotel or beach resort with organized activities like m...

25-07-2016 | Compared to analog audio amplifiers like Class-A, -B and -AB, digital Class-D amplifiers have much higher power efficiency allowing them to...

11-03-2015 | Up until now we only had digital T-Boards. Why not an analog one? We asked ourselves what could be a useful circuit when experimenting with...

28-05-2013 | It all started with the Measurement Filter for Class D (100540-1) published in issue 415, July/August 2011. It was designed to handle large...

8-03-2013 | With this project, I like to build a small class D amplifier based on a 555 timer IC. I also like to use only “common” components, so this p...
