Abstract
In this paper two novel distinct transimpedance filter topologies are described. The first one is based on the well known multiple feedback (MFB) filters while the second resembles typical Q-enhancement configurations. For both classes low- and band-pass responses have been fully developed taking into consideration several parameters: frequency response, input-output impedances and noise. Q-enhancement filters have been found to be more versatile if several parameters are to be optimized, at the expense of using more amplifiers. Transimpedance filters find direct application in some sensors and D/A converters which provide current as an output signal.
