Logarithmic Analog-digital Converters. Review

In this work, a review of logarithmic analog-to-digital converters (LADCs) was carried out and an analysis of their properties in the dynamic range of input signals of 80 dB was carried out. It is shown that the highest metrological characteristics are obtained by LADCs on switched capacitors (CC) using high-quality analog switches from Maxima and Analog Devices companies, in which parasitic interelectrode capacitances do not exceed 1 pF. LADC of different classes were considered.

THE ROLE OF BUILDING INFORMATION MODELING TECHNOLOGIES IN ARCHITECTURAL EDUCATION

The article provides a detailed analysis of the role of building information technologies in the professional training of first-level (bachelor’s) degree students in the 191 "Architecture and Urban Planning" program at the Institute of Architecture and Design, Lviv Polytechnic National University. Special attention is paid to the study of the role of modern technologies in shaping the key skills and professional competencies of future architects.

Recurrent Logarithmic Analog-Digital Converters With a Constant Logarithm Base

In this work, a new conversion method is proposed, which makes it possible to implement recurrent logarithmic analog-to-digital converters (LADCs) with a constant base of the logarithm $(\zeta)$, in which the reference voltages are formed using a reference voltage divider composed of identical $L-$shaped links of resistors $R-R^{\prime \prime}$ and additional resistor $R^{\prime}$, and the values of the resistors are set according to the formulas
$R^{\prime}=\frac{\zeta}{1-\zeta} \cdot R$ and $R^{\prime \prime}=\frac{\zeta}{(1-\zeta)^2} \cdot R$.
