On the sensitivity of band-pass active filters using one or two amplifiers
Tadashi Ae, KAORU NAKANISHI · International Journal of Electronics · 1976
As is well known, the active filter using one or two amplifiers is practicable for the realization of the second-order transfer function. At this time several configurations are possible for each transfer function (e.g. high-pass, band-pass, or low-pass). In this paper we discuss some types of band-pass active filters with one amplifier (§ 2), and with two amplifiers (§ 3).
