In this two-part “Filter Wizard”, we’ll look at some fundamental noise mechanisms in filters, using SPICE to illustrate the performance limits you can expect. We’ll concentrate on analog filters in ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Analog filters implemented in CMOS technology continue to be a cornerstone in the development of modern electronic systems. By integrating active components such as operational transconductance ...

One of the major difficulties in studying electricity, especially when compared to many other physical phenomena, is that it ...

Differences between digital and analog triggering. Advantages of digital triggering. How to tell what type of triggering is used by an oscilloscope. An oscilloscope’s trigger function, which ...

Semiconductor Engineering sat down to discuss what’s changing in analog design with the shift toward heterogeneous integration and more safety- and mission-critical applications with Mo Faisal, ...

You know what’s great? Magnets. You know what’s equally great? Filtered photos. Which makes this little DIY project – using both magnets and homemade filters – double great, right? Right guys? If you ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

In Part 1 of this pair of articles, we ran SPICE noise simulations on a simple second order lowpass filter. We saw that there is something fundamental about the ‘hold’ that the filter’s capacitor ...
