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 ...

In a world of digital electronics, there are still necessary functions for analog circuits, especially filters. When real-world signals are digitized or synthesized, for example, analog filters are ...

Why a tunable GHz-range filter is needed. How a new approach to devices based on YIG and magnetic spin waves offers a much smaller and lower-power solution. How the new device was implemented along ...

A digital replacement for analog intermediate frequency (IF) filtering, such as that applied in spectrum analyzers, can now be obtained as a block of intellectual property (IP). And, that IP can be ...
