Abstract: The disclosed invention provides a structure and method for easily measuring capacitive and/or resistive components of a sensor system. In one embodiment, the structure comprises a signal generator configured to output a load current to a measurement element containing measurement sensor elements and a parasitic capacitance. A controllable excitation voltage is generated, via integration of the load current on the parasitic capacitance, and output to the measurement sensor elements having capacitive and resistive components. The controlled voltage through the measurement device may be manipulated to cause the capacitive and resistive components to exhibit a transient effect. The resulting output current, provided from the measurement device therefore has transient response characteristics (e.g., the settling time, amplitude) that can be selectively measured by a measurement circuit to easily determine values of the capacitive and resistive measurement elements. Furthermore, dedicated demodulation techniques may be used to measure the capacitive and resistive components.

Abstract: One embodiment of the present invention relates to a magnetic sensor circuit having a magnetic field sensor device configured to generate a digital signal proportional to an applied magnetic field. An analog-to-digital converter converts the analog signal to a digital signal that is provided to a digital signal processing unit, which is configured to digitally track the analog output signal. The digital tracking unit comprises a delay removal circuitry configured to generate a plurality of digital signal component corresponding to a chopping phase. A non-delayed offset compensated digital output signal may be generated within the chopping phase by mathematically operating upon (e.g., adding or subtracting) the plurality of digital signal components, generated by the delay removal circuitry.
