✦ Synopsis
The present papei describes a logarithmic A/D converter (LADC) working with the charge redistribution principle. The LADC uses a serial and a parallel capacitive attenuator and is suitable for manufacturing o n a single chip. Formulae for the values of the capacitors are given in terms of the base of logarithm used. This LADC uses logarithmically spaced voltage comparison levels and therefore eliminates the use of logarithmic analogue signal conditioning circuits.
