A method of calculating at least one sensor modelling coefficient for multiple sensor regions of operation includes defining a first sensor region of operation and a further sensor region of operation, and calculating the sensor modelling coefficient for the first sensor region of operation. A derivative equation then is derived for the further sensor region of operation based at least partly on at least one defined inter-region boundary constraint. The sensor modelling coefficient is calculated for the further sensor region of operation based at least partly on the derivative equation.

A method of calculating sensor modelling coefficients includes determining a preliminary coefficient value for a first sensor modelling coefficient, calculating a coefficient value for a further sensor modelling coefficient using the preliminary coefficient value for the first sensor modelling coefficient and a data measurement value, and calculating a refined coefficient value for the first sensor modelling coefficient using the calculated coefficient value for the further sensor modelling coefficient and the data measurement value.

Method and circuit for calculating sensor modelling coefficients

A data acquisition system for converting an analog input signal to a digital output signal includes a programmable gain amplifier (PGA), an analog to digital converter (ADC), and an averaging module. The PGA generates first and second amplified signals during respective first and second conversion cycles. The first and second amplified signals include respective first and second amplified input signals and first and second sets of offset and noise signals. The first and second amplified input signals have the same polarities, and the first and second sets of offset and noise signals have opposite polarities. The ADC generates first and second digital samples corresponding to the first and second amplified signals respectively and the averaging module averages the first and second digital samples to eliminate the first and second sets of offset and noise signals from the digital output signal.
