Abstract :
This brief reports a current-mode LP, HP and BP filter which ideally exhibits zero input and very high output resistance. All active and passive sensitivities are no more than one half in magnitude. The filter employs a minimum number of passive elements, only two capacitors and two resistors, and two filter functions can simultaneously be realized.
