Low frequency, current mode programmable KHN filters using large-valued active resistors
(2007)
The present work proposes a new current-mode, programmable Kerwin Huelsman Newcomb (KHN) filter suitable for very low frequency processing. The proposed implementation, developed with only six current mirrors and two ...

A very compact KHN filter with multidecade tuning
(2007)
A very compact implementation of a multifunction Kerwin Huelsman Newcomb (KHN) filter that can be frequency tuned almost seven decades, from 0.2 Hz to 1 Mhz, is presented. Tuning is achieved by means of high-value, ...
