Abstract
The electronic measurement circuit comprises a measurement sensor with two differential mounted capacitors each comprising a fixed electrode, and a common electrode arranged to move relative to the fixed capacitor electrode to alter the capacitive value when the physical parameter is measured. The circuit further comprises a first integrator unit connected to the common electrode for integrating charge received from the sensor, and comprising two integrators arranged to be connected alternately to the common electrode, a first comparator for comparing analogue output values from the first integrator unit, a second integrator unit for integrating charge received from the first integrator unit, a second comparator for comparing analogue output values from the second integrator unit, a switch circuit for switching different voltage values across the capacitors, and a feedback circuit for feeding a digital output signal from the first comparator to the switch circuit for controlling its operation, and an incremental calculation unit receiving digital output signals from the comparators and supplying a final digital output signal.
