Abstract: Various apparatuses and methods are described where a signal is amplified using a chopper amplifier arrangement, and ripples caused by said chopper amplifier arrangement are reduced. In some cases, this reduction of ripples is performed by controlling a voltage offset of an amplifier of said chopper amplifier arrangement. In other embodiments, a detection of ripples or a chopping of the chopper amplifier arrangement is at least temporarily disabled.

Abstract: A stress sensor includes a semiconductor substrate with a first transistor arrangement and a second transistor arrangement. The first transistor arrangement includes a first transistor with a first source-drain channel region and a second transistor with a second source-drain channel region. The first transistor and the second transistor are aligned relative to each other such that the current flow directions in the first and the second source-drain channel regions are opposite to each other. The second transistor arrangement includes a third transistor with a third source-drain channel region and a fourth transistor with a fourth source-drain channel region. The third transistor and the fourth transistor are aligned relative to each other such that the current flow directions in the third and the fourth source-drain channel regions are opposite to each other. The stress sensor generates a gradient-compensated output signal used to determine a mechanical stress acting on the semiconductor substrate.

Abstract: Methods and apparatuses for comparing redundant signals in functional safe systems are provided, including methods for mitigating differing signal path delays and for signal weighting of the redundant signals are proposed. An Apparatus includes a first signal path for a first measurement signal of a physical quantity, the first signal path having a first signal propagation delay; a second signal path for a second measurement signal of the physical quantity, the second signal path having a second signal propagation delay different from the first signal propagation delay; a delay compensation circuit configured to compensate for a difference between the first and second signal propagation delays to generate delay-compensated first and second measurement signals; and comparison circuitry configured to compare the delay-compensated first and second measurement signals.

Abstract: An integrated circuit has an oscillator circuit having an on-chip oscillator, a digital phase locked loop and a sensor. A frequency of an output signal from the oscillator circuit is adjustable. The digital phase locked loop receives the output signal from the oscillator circuit at an input and a synchronization signal based on an output signal from an external precision oscillator in the form of a crystal oscillator or MEMS oscillator at an external interface and generates a control signal in order to synchronize the frequency of the oscillator circuit with the frequency of the external crystal oscillator. The sensor is designed to measure at least one environmental parameter, wherein the digital phase locked loop is designed to take into account the at least one measured environmental parameter when generating the control signal.

Abstract: Magnetic field sensors and sensing methods are provided. A magnetic sensor includes at least one magnetic field sensor element configured to generate an analog input sensor signal in response to a magnetic field, an inverting amplifier configured to generate an analog output sensor signal having a gained value with respect to the analog input sensor signal, a programmable current divider disposed in a negative feedback path of the inverting amplifier such that the gained value is dependent on an effective feedback resistor value of the programmable current divider, and a digital controller configured to receive at least one measurement parameter, generate a codeword based on the at least one measurement parameter, and transmit the codeword to the programmable current divider for compensating the gained value. The effective feedback resistor value is adjusted based on the codeword received by the programmable current divider.
