Abstract

An inherent characteristic of most translinear (TL) filters is instantaneous companding. This brief describes a distortionless syllabic companding TL filter based on the "analog floating-point technique" [1]. Through the addition of a compensation current to each of the capacitances in the filter, distortion is eliminated. By applying syllabic companding to a TL filter, the input current can be much larger than the quiescent current, thus increasing the dynamic range. © 1998 IEEE.
