A Simple Bridge Resistance Deviation-to-Frequency Converter for Intelligent Resistive Transducers
Po Lee, Won-Sup Chung, Sang‐Hee Son · Journal of IKEEE · 2008
A bridge resistance deviation-to-frequency (BRD-to-F) converter is presented for interfacing resistive sensor bridges. It consists of a linear operational transconductance amplifier (LOTA), a current-controlled oscillator (CCO). The prototype converter was simulated using commercially available discrete components. The result shows that the converter has a conversion sensitivity amounting to 16.90 kHz/ and a linearity error less than 0.03 %.
