Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...
Setting out to design a higher order, high pass filter using the Sallen-Key single op amp topology will immediately run into a question of required amplifier bandwidth. This is most often set by the ...
Traditionally, power engineers are trained to think in the time-domain while RF engineers are trained to think in the frequency-domain. To successfully design high-frequency DC-DC converters, the ...
