When multistage designs are intended using low power op amps, the load presented by a poorly designed stage might in fact impair the intended signal frequency response above the high pass corner. Some ...

Until recently, audio systems have largely been analog. Now the trend is moving rapidly to digital implementations. While the literature contains most of the information needed to design and implement ...

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 ...

The low-frequency LC performance of a high-pass filter is strongly affected by the quality of the filter components. Typically, the inductor is the component that deviates most significantly from the ...
