A general domain CMOS companding integrator

Proceedings of the 19th annual symposium on Integrated circuits and systems design, 2006
This work presents a new architecture of companding integrator for application in CMOS current-mode filters. Since MOS transistors can operate in the whole inversion region, this circuit can be classified either as log-domain or as square-root domain. Due to the higher bias currents allowed, signal-to-noise(distortion) ratio is improved in comparison ...

Instantaneously companding integrators

Proceedings of 1997 IEEE International Symposium on Circuits and Systems. Circuits and Systems in the Information Age ISCAS '97, 2002
The concepts behind instantaneously companding integrators are reviewed, and the context in which they may find use is discussed. Several examples of specific cases are offered, including log domain, square root domain and variable capacitance circuits. Several issues requiring attention are discussed.

Multidimensional companding quantization of the gaussian source

IEEE Transactions on Information Theory, 2003
Summary: Multidimensional companding quantization is analyzed theoretically for the case of high-resolution and mean-squared-error distortion. The optimality of choosing the expander function to be the inverse of the compressor function is established first. Heuristic derivations of the point density and moment of inertia of companding are given, which

CMOS Current-Mode Companding Divider

IEICE Transactions on Electronics, 2009
A CMOS current-mode companding divider is presented. Currents of both dividend and divisor are compressed into log-domain. Then the logarithm current of divisor is subtracted from the logarithm current of dividend. After expanding the subtraction result, the division function could be achieved.

Companding and PCA compression of spectrum sets

Proceedings. 2005 IEEE International Geoscience and Remote Sensing Symposium, 2005. IGARSS '05., 2005
Companding is a procedure which can be used to smooth the effects of the fluctuating signal energy. The effect of the compressor in the transmitter is compensated with the expander in the receiver. PCA is an essential part in the lossy compression of the spectral images. In this paper we combine these two techniques to study the effect of companding in
