Abstract: A magnetic field sensor is disclosed for providing an output signal in response to an external magnetic field. The sensor comprises a primary magnetic field transducer for producing a primary signal in response to the external magnetic field and having a first magnetic field saturation characteristic; a secondary magnetic field transducer for producing a secondary signal in response to the external magnetic field and having a second magnetic field saturation characteristic. The first magnetic field saturation characteristic is different from the second magnetic field saturation characteristic. The sensor is configured to use the secondary signal to correct for errors in the output signal arising from saturation of the primary transducer.

Abstract: A resistive sensor includes a current input sigma-delta converter that uses a switched offset voltage source to provide scalable gain and more linear operation. The sigma-delta converter includes an integrator, a quantizer, and a decimator. In one embodiment, the resistive sensor and offset voltage source are coupled to provide an input current at a first node. The integrator has a first input terminal coupled to the first node, and an output terminal. The quantizer has a first input terminal coupled to the output terminal of the integrator, a second input terminal for receiving a clock signal, and an output terminal coupled to provide a feedback signal to control the offset voltage source. The decimator has an input terminal coupled to the output terminal of the quantizer, and an output terminal for providing an output signal. The switched offset voltage source provides scalable gain and good linearity.

Abstract: An analog to digital circuit that includes a feedback circuit with a return to open (RTO), digital to analog converter (DAC) that provides an analog signal that is indicative of an output of an ADC component of the ADC. During a data phase, the output of the DAC is provided to a combiner input through a resistive circuit. The combiner also receives an analog input signal at another input and provides a combined output signal to the ADC component. During a reset phase, the output of the DAC is provided to the combiner through a lower resistance bypass circuit to bypass the resistive circuit.
