Abstract
A novel thermistor-based temperature-to-frequency converter, using a delay network, is described which exhibits linear input/ output relation over the range 253-523K with a conversion sensitivity of 14.7 Hz/K and maximum deviations of 4.8 percent at 523K and 1.2 percent at 248K. Analytical expressions for system performance are obtained and verified experimentally. The circuit adjustment is performed simply and quickly at room temperature.
