Driving an analog-to-digital converter (ADC) for optimum mixed-signal performance is a design challenge. Figure 1 shows a standard ADC driver circuit. During ADC acquisition time, the sampling ...

One of the jobs of a circuit designer is to build a measurement system that provides valid input-to-output data as defined by the system requirements over a given frequency range. The four possible ...

Low-pass filters (LPFs) are fundamental components in modern electronic systems, serving to permit signals below a designated cutoff frequency while attenuating higher frequencies. Recent advances ...

Binary search, a decrease-and-conquer approach, plays an important role in testing today�s low-pass filters. When testing a low-pass filter, generally you have to use an arbitrary waveform generator ...

If you are in any way connected with radio, you will have encountered the low pass filter as a means to remove unwanted harmonics from the output of your transmitters. It’s a network of capacitors and ...

Noise is a common and pervasive problem in electronics design and debug. At one time or another, almost every designer and debugger of electrical circuits will spend some time dealing with ...

My previous column described the Sallen-Key circuit for a low-pass filter. At times, you will not find a low-pass filter with the specifications you need in an anti-alias circuit, so you might decide ...
