20100019844 | HIGH EFFICIENCY PRECISION AMPLIFIER - A high efficiency precision amplifier which comprises a linear amplifier stage, a class D amplifier stage and a set of switches is provided. Both amplifier stages receive the same input signal. The load is driven by the output of the linear amplifier stage. The set of switches connect the output of the class D amplifier stage to either of the positive and negative supply terminals of the linear amplifier stage and the other of the positive and negative supply terminals of the linear amplifier stage to a negative or positive supply, depending on the polarity of the signal being amplified. | 01-28-2010 |

20140184214 | MAGNETIC FIELD SENSOR LINEARIZATION ARCHITECTURE AND METHOD - A method of processing an output signal and a readout circuit for a magnetic field sensor are disclosed. The purpose of the readout circuit is to generate a digital representation of the magnetic field vector strength. It comprises an input stage for receiving an output signal of the magnetic field sensor; an output stage for outputting a digital output signal corresponding to the sensor output signal; and an analog to digital conversion circuit. The analog to digital conversion circuit receives the sensor output signal and performs, in sequence, a fast conversion process for calculating a number of most significant bits of the digital output signal corresponding to the sensor output signal and for generating a compensation signal, and a delta sigma based conversion process for calculating at least one least significant bit of the digital output signal. The compensation signal is fed back to the sensor input for linearization. The delta sigma based conversion takes advantage of oversampling and noise shaping to increase resolution. | 07-03-2014 |

20150105630 | HEART PULSE MONITOR INCLUDING A FLUXGATE SENSOR - A heart pulse monitor includes a permanent magnet including a mounting structure for securing the permanent magnet in displaceable contact with a blood vessel of a wearer. The permanent magnet has a thickness defining an axial direction that the permanent magnet is displaceable when blood flows. A fluxgate sensor system is positioned a distance in the axial direction from the permanent magnet to sense an axial magnetic field therefrom. The permanent magnet displaces in the axial direction upon a heart pulse of the wearer resulting in a change in the axial magnetic field which is sensed by the fluxgate sensor system through a change in an induced AC output signal on the sense coil. A processor is coupled to receive information from the induced AC output signal. The processor implements calibration data which converts information from the induced AC output signal into a heart pulse measurement for the wearer. | 04-16-2015 |
