摘要： A method of offset calibration in a SAR ADC (200) comprising the steps of: determining a number of bits of an analog input signal (V IN ); detecting if a binary code determined from the analog input signal (V IN ) matches at least one trigger code; using at least one setting code to determine a calibration bit (B * LSB ; B* MSB ); analyzing a bit of the digital signal (C OUT ) and the calibration bit (B * LSB ; B* MSB ); determining an indication of a presence of offset error; and calibrating the offset error. As the determination of the calibration bit (B * LSB ; B * MSB ) requires only one additional comparison, when compared to the normal operation, the normal operation does not need to be interrupted. Therefore, the calibration can be done in the background and, as such, can be performed frequently thereby taking into account time-varying changes due to environmental effects.

摘要： An ion sensor (300) for sensing an ion concentration in a bulk solution comprises a reference electrode (310) embedded in an reference electrolyte solution (340), and a first ion selective electrode (320). The ion sensor (300) moreover comprises a second electrode (330) sensitive to the reference ions or to an ion different from the ion to be measured, whereby the second electrode (330) is in direct contact with the bulk solution when the ion sensor is immersed therein. The potential difference (V 1 ) between the first electrode and the reference electrode is a measure for the ion concentration in the bulk solution and is corrected with the potential difference (V 2 ) between the second electrode and the reference electrode to compensate for the drift of the reference electrode (310).

摘要： Described herein is a multi-channel biopotential signal acquisition system (900) in which a plurality of biopotential channels is corrected for common-mode interference. Each biopotential channel comprises an electrode (910, 920, 930, 940) for providing a biopotential input signal and an associated amplifier (950, 960, 970, 980) for amplifying the biopotential input signal and for providing a biopotential output signal (955, 965, 975, 985) that is processed in a processor (250, 260, 270, 990). Each biopotential output signal (955, 965, 975, 985) is passed to a common-mode feedback system (810) that determines an average common-mode signal and feeds that signal back to each of the amplifiers (950, 960, 970, 980) in each of the biopotential channels to enhance common-mode rejection ratio of the system (900).
