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 ...

Analog filters implemented in CMOS technology continue to be a cornerstone in the development of modern electronic systems. By integrating active components such as operational transconductance ...

Analog filters using inductors, capacitors, and resistors are critical to most circuits and systems. Whether as passive or active designs, it sometimes seems that they have been studied “to infinity ...

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, ...
