The technique generates an oscillating signal using a variable resistance sensitive to a variable parameter. A frequency of the oscillating signal is directly dependent on the variable resistance. A time-to-digital converter generates a digital code indicative of the variable resistance. The digital ...
A novel temperature difference-to-frequency (TD/F) converter using two platinum resistance temperature detectors (RTDs) has been developed. The resistance difference of two RTDs is converted into a DC current to control the simulated inductor, which is designed so that its inductance is inversely ...

In this work, an interface circuit applied to resistive gas or chemical sensors is proposed. The interface circuit includes a detection front-end, a single-end to differential circuit, a successive approximation analog-to-digital converter (SAR ADC), and some reference auxiliary circuits. In detect...
