description

Abstract In this work a difference temperature-to-time converter is shown using two thermistors working in a DC generalized impedance converter. Voltage drop in one of the thermistors depends on the temperature difference between them. This voltage is compared with a time varying exponential reference voltage obtaining a time interval at the output circuit with good linear dependence with respect to the input temperature difference. Experimental results are obtained showing a new generalized impedance converter application. The implemented circuit was characterized by a repeatability of 1.0%, a reproducibility of 4.5% and a relative accuracy of 1.3%.
