Abstract :
A method for the design of differential current-mode wave active filters, which is based on the use of single-ended wave port terminators, is presented in this paper. The resulting filters are modular and very simple to design while their cutoff frequency is controlled by a dc current, giving them the ability of frequency tuning. As an example a wide-band bandpass filter is realized by cascading a low-pass and a highpass filter. The overall filter has been integrated using a standard 0.35-μm CMOS technology.
