- 論文の詳細を見る
A bridge resistance deviation-to-time interval converter is presented for interfacing resistive sensor bridges. It consists of two voltage-to-current converters, two current-tunable Schmitt triggers, a ramp integrator, and two logic gates. A prototype circuit built using discrete components exhibits a conversion sensitivity amounting to 4527.8µs/Ω over the resistance deviation range of 0-2Ω and a linearity error less than ± 0.01%.
