A proposed resistance-to-time converter with switching impulse calibrators for resistive bridge sensors
This paper presents a simple resistance-to-time converter. It consists of two voltage comparators, a ramp voltage generator, two logic gates and impulse voltage calibrators. A square-wave generator circuit is suggested in this paper. The design is simple and independent of the OPAMP offset issue...

| Summary: | This paper presents a simple resistance-to-time
converter. It consists of two voltage comparators, a ramp voltage
generator, two logic gates and impulse voltage calibrators. A
square-wave generator circuit is suggested in this paper. The
design is simple and independent of the OPAMP offset issues.
The resulting square-wave is rectified to get its DC equivalent
and to a triangular output; the two outputs are applied to a
comparator for generating a digital output with duty cycle
proportional to a change in resistance upon which is dependent
the DC. |
