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 ...
Tempe, Ariz.—Anadigm has launched AnadigmFilter1, the first in a family of chipsets using its dynamically programmable analog signal processor (dpASP) designated the AN231E04 and its AN236C04 state ...
Analog filters play an important part in electronic signal synthesis subsystems, providing functions such as antialiasing and noise filtering for A/D converters (ADCs), as well as “reconstruction” ...
Current‐mode all‐pass filters represent a crucial class of signal processing circuits that, by utilising current signals rather than voltage signals, offer inherent advantages in terms of integration, ...
This amplifier-based IC implements dual low-pass filters with matched response at cutoff frequencies up to 10 MHz. To build active filters for high-frequency RF applications, designers may construct ...
