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, ...

I’m glad that some of my readers were able to spot the ‘problem’ with the lowpass filter we ended up with at the end of “Gee, I see! The Ins and Outs of Generalized Impedance Converters” First to get ...
