Logarithmic ADC with accumulation of charge and impulse feedback – construction, principle of operation and dynamic properties

Zynovij Mychuda, Lesya Mychuda, Uliana Antoniv, Adam Szcześniak


This article is a presentation of the analysis of new class of logarithmic analog-to-digital converter (LADC) with accumulation of charge and impulse feedback. LADC construction, principle of operation and dynamic properties were presented. They can also be part of more complex converters and systems based on LADC. LADC of  this class is perspective for implementation in the form of integrated circuit, as the number of switched capacitors needed to conversion is minimized to one capacitor.
