Consumer requirement for fewer wires connecting their home entertainment systems is driving up the demand for wireless active speakers. In order to achieve the best audio quality from high end active ...

What do you really get using a supplier tool for an multiple feedback (MFB) low pass active filter? Let's continue the quest for the best results using the example designs from Part 1. In this online ...

Today I am experimenting with a single chip Universal Active Filter, in this case I made a small PCB for the UAF-42 from Texas Instruments. I chose this part in particular as it facilitates setting ...

Logic Noise is an exploration of building raw synthesizers with CMOS logic chips. This session, we continue to abuse the 4069UB as an amplifier. We’ll turn the simple unity-gain buffer of last session ...

Texas Instruments (TI) has unveiled what it claims is the industry’s first stand-alone active electromagnetic interference (EMI) filter integrated circuits (ICs). Intended to help engineers implement ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...
