Recurrent logarithmic ADCs

This work is dedicated to the investigation of errors in the recurrent logarithmic analog-to-digital converters (LADC). A generalized structural diagram of the recurrent LADC with a variable logarithmic base is provided. The implementation features and operating principles are explained. Models of the recurrent LADCs that account for the influence of component leakage currents in the converter circuits have been developed. The models consider changes in the structure of the recurrent LADCs during the conversion process.

This work is devoted to the study of the features of the implementation of recurrent logarithmic analog-to-digital converters (LADC). The general principles of construction of recurrent LADCs are outlined. The implementation of recurrent LADC with a constant and a variable in the process of converting the base of the logarithm is considered. Generalized structural schemes of the recurrent LADCs are given, and their accuracy and speed of operation are evaluated.
