Resistive-bridge sensors are widely used in various sensor systems. There are many sensor signal conditioners from different manufacturers for such sensing elements. However, no one existing on the modern market integrated converter for resistive bridge sensors can work with both: resistivebridge sensing elements and resistive-to-frequency and -duty-cycle converters' outputs. A proposed and described in the article universal interface for resistive-bridge sensing elements and bridge-output-tofrequency and/or duty cycle converters based on the designed Universal Sensors and Transducers Interface (USTI) integrated. It is based on a simple, cost effective three-point measuring technique and does not require any additional active components. The USTI IC is realized in a standard CMOS technology. The active supply current at operating voltage +4.5 V and clock frequency 20 MHz is not more than 9.5 mA This paper reports experimental results with a strain gauges bridge emulator and differential pressure resistive bridge sensor SX30GD2. © 2011 IFSA.

Light-to-frequency converters are widely used in various optoelectronic sensor systems. However, a further frequency-to-digital conversion is a bottleneck in such systems due to a broad frequency range of light-to-frequency converters' outputs. This paper describes an effective OEM design approach, which can be used for smart and intelligent sensor systems design. The design is based on novel, multifunctional integrated circuit of Universal Sensors & Transducers Interface especially designed for such sensor applications. Experimental results have confirmed an efficiency of this approach and high metrological performances. © 2012 IFSA. Source

Cost reduction in wireless sensor networks becomes an important requirement to extend their application in fields where a great amount of sensors is needed. Traditional approach to use multichannel analog-to-digital converter and/or analog multiplexers for analog sensors will not give any reduction in price. Moreover, the analog multiplexer introduces additional measuring error. This article describes in details the developed advanced, robust but cost-effective sensor nodes' architectures suitable for further integration in a node-on-chip. Such sensor nodes can work with any analog and quasi-digital sensors and transducers, and its sensing sub-system lets achieve the best metrological performances. A comprehensive comparative study of sensor node's architectures and sensing sub-systems are presented. © 2013 IFSA. Source
