【 摘 要 】

References(5)Cited-By(1)A simple resistance-to-time converter is presented for interfacing resistive bridge sensors. It consists of two voltage comparators, a ramp voltage generator, and two logic gates. A prototype circuit built using discrete components exhibit a conversion sensitivity amounting to 2832.4µs/Ω over the resistance deviation range of 0-2Ω and a linearity error less than 0.005%. Power dissipation of the converter is 15.57mW.
