Analog filters play an important part in electronic signal synthesis subsystems, providing functions such as antialiasing and noise filtering for A/D converters (ADCs), as well as “reconstruction” ...

There comes a time in every electronic designer’s life when, whether they know it or not, they need an analog filter in their design. If you’re coming from a digital background, where everything is ...

Delta-sigma converters with sinc (sinx/x) digital filters change the signal chain’s complex antialiasing-filter requirements to a simple, first-order, passive filter. With this “easy-to-design” ...

The design of analog active filters has evolved from manual component selection to sophisticated optimisation frameworks. Classic topologies—Bessel, Butterworth, Chebyshev and elliptic—provide ...

A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...

Today’s electronic chips are commonly comprised of a mix of analog, RF, and digital components, with increasing functionalities, complexities, and numbers of transistors reaching the trillions. While ...
