This book develops voltage-to-frequency converter (VFC) solutions integrated in standard CMOS technology to be used as a part of a microcontroller-based, multisensor interface in the environment of portable applications, particularly within a WSN node.

Covers complete design flow of the main blocks used in voltage-to-frequency converter circuits (voltage-to-current converters, bidirectional current integrators, control circuits and bias circuits) Describes implementation of all circuits in CMOS technology, considering low-voltage low-power restrictions Includes novel blocks and techniques to achieve a rail-to-rail operation in the voltage-to-current converters, and therefore in the VFC Includes supplementary material: sn.pub/extras
