With newer precision Fully Differential Amplifier’s (FDA’s) providing more than 800Mhz Gain Bandwidth Product (GBW), the available frequency range for active filter designs combined into the last ...

Active filters are ubiquitous in electronic design today, performing signal-frequency manipulation and conditioning for audio, IF (intermediate frequency), and digital-signal processing. The success ...

Intersil has introduced a free online design tool for op amp active filter designs. Dubbed the iSim, the active filter design tool provides the user with a ranked list of possible amplifiers that fit ...

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 ...

A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
