This article is part of the Ideas for Design Series: Vol. 3, No. 9. Many communications and sensor applications require a bandpass filter with wide bandwidth. This filter typically requires precision ...

Hardware-design engineers have long recognized the usefulness of RC lowpass filters (Figure 1). Lowpass filters are useful for performing signal conditioning, removing noise from a signal, or ...

For many analog-to-digital converter (ADC) applications, a simple passive resistor/capacitor (RC) filter at the buffer input will provide adequate antialiasing filtering. However, an active filter is ...
