Rail-to-rail signal transducers for USB sensor devices

Abstract

Design principles and microelectronic parts of sensor devices signal transducers (including thermomagneto-, photo- measuring converters) meeting requirements of up-to-date low-voltage energy-efficient apparatus driven and fed through USB port are considered. It is shown that such sensors in order to providing high technical characteristics have to have possibility of highprecision functional transductions at low-voltage unipolar supply source (5 V or less), consume small power (tens of mW or less) and be compatible with USB interface.
