Abstract
An inherent characteristic of most translinear (TL) filters is instant aneous companding. This brief describes a distortionless syllabic comp anding TL filter based on the ''analog floating-point technique'' [1], Through the addition of a compensation current to each of the capacit ances in the filter, distortion is eliminated, By applying syllabic co mpanding to a TL filter, the input current can be much larger than the quiescent current, thus increasing the dynamic range.
