Novel transimpedance filter topology for instrumentation

In this paper, a novel transimpedance filter topology is described. It resembles typical Q-Enhancement configurations. Low- and band-pass responses have been fully developed taking into consideration several parameters such as frequency response, input-output impedances and noise. Design conditions are obtained to optimize the performance. Transimpedance filters find direct application with some sensors and D/A converters which provide a current as output signal, avoiding a current to voltage conversion.
