Transactions Briefs An Instantaneous and Syllabic Companding Translinear Filter
نویسنده
چکیده
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.

Syllabic-Companding Log Domain Filters
A general theory for companding log domain filters is proposed which combines not only exponential mappings, but also a new translational mapping approach which guarantees suitable operating conditions in any log domain filter. The filter equations resulting from the use of the theory ultimately contain translinear terms which are known to be realizable using translinear techniques. A discussio...
متن کاملNoise Considerations for Translinear Filters
Translinear filters exhibit unconventional noise characteristics, due to the internal nonlinear behavior. In this paper, the maximal signal-to-noise-ratio and the dynamic range properties of translinear filters are discussed, and the relation between these two specifications and the inherent instantaneous companding is described.
متن کاملNonlinear Analysis of Noise in Static and Dynamic Translinear Circuits
For translinear filters, or log-domain filters, calculation of the maximal signal-to-noise-ratio, an important filter specification, is not trivial, due to the inherent companding behavior and the nonstationary nature of the transistor noise sources. To address this issue, a nonlinear noise analysis method is proposed. Based on large-signal calculations, expressions for the first-order noise an...
متن کاملDetermination of the steady-state behaviour of the state variables of a second-order filter with syllabic companding
In order to get a better understanding on the concepts of dynamic eigenvalues and dynamic eigenvectors as presented in [1], the steadystate behaviour of the state variables of the filter with syllabic companding described in [2] is determined. For that purpose, the approach presented in [3] is used. Some comments are made regarding the general form of the solution of the Riccati equation involv...

Introduction: One of the possible techniques to cope with the restrictions imposed by llow supply voltages is instantaneous companding [l], which is an inherent characteristic of translinear (TL) filters [2], also called exponential state-space filters [3]. TL filters exploit the exponential large-signal behaviour of the bipolar, or weak inversion MOS, transistor both for an expanding capacitan...
