Abstract
In this paper, a novel transimpedance filter topology is described. It resembles typical Q-Enhancement configurations. Low-and band-pass res ponses have been fully developed taking into consideration several par ameters such as frequency response, input-output impedances and noise. Design conditions are obtained to optimize the performance. Transimpe dance filters find direct application with some sensors and D/A conver ters which provide a current as output signal, avoiding a current to v oltage convertion.
