A charge pump is connected between a source and a body of the switch. Such a configuration avoids a condition in which the body diode opens for negative drain-to-source voltage (Vds) across the switch. Such a configuration also avoids a condition in which the switch control circuit generates control signals referenced to a body potential rather than a source potential, thereby allowing the switch to reliably turn off even for negative Vds. An additional gain stage ensures that the switch can be properly turned on. The techniques can be used to generate switches that enable highly linear processing of bipolar differential signals even far outside of the supply range.

Abrégé

The present disclosure provides a linear actuator apparatus, magnetic sensor system and method of use for detecting a position of a component driven by a rotatable mechanism in a linear direction. A magnetic sensing device comprising both a multi-turn (MT) sensor and a single turn (ST) sensor is provided within the same semiconductor package and placed in the vicinity of the rotatable mechanism. A magnet is mounted on the rotatable mechanism, such that, as the mechanism rotates, a rotating magnetic field is generated. The MT sensor measures the number of turns of the rotating magnetic field, which is translated to the number of turns of the rotatable mechanism. The ST sensor measures the angle of the rotating magnetic field, which is translated to an angular position of the rotatable mechanism. As each turn of the rotatable mechanism will be translated to a specific amount of linear motion, the amount by which the rotational mechanism has turned is proportional to the distance travelled by the driven component, and thus indicative of the linear position. Therefore, by placing a magnet and the magnetic sensing device in relation to the rotatable mechanism, with the multi-turn sensor providing the number of turns and the angle sensor providing the precise angular position within each turn, the measured rotational position can be translated to a corresponding linear position of the element being moved linearly as a result of the rotation.

The present disclosure provides a device for initializing a multi-turn sensor that initializes the sensor almost instantaneously, thereby consuming very little energy. The initialisation device is provided in the form of a conductor that is placed a small distance above or below the sensor spiral, the conductor being configured so that it crosses at least two opposing corners of the spiral. A current is then applied to the conductor to generate a magnetic field in the corner sections of the spiral to nucleate domain walls. Once the domain walls have been nucleated, the external magnetic field will drive the pairs of domain walls away from each other towards the adjacent corners, changing the magnetic alignment of the tracks as they pass through. As such, the spiral can be initialised very quickly by applying a current to the conductor in the correct direction.

The present disclosure relates to a configurable output stage for a DAC channel. The output stage receives an analog output from a DAC and outputs a signal to an output terminal. The output stage is configurable between a voltage mode and a current mode. In the voltage mode, the output stage supplies the analog signal to the output terminal as a voltage signal. In the current mode, the output stage supplies the analog signal to the output signal as a current signal. The output stage can receive user input to select the desired mode. Consequently, an integrated circuit can be implemented with multiple DAC channels, each having the configurable output stage. A user can choose how many channels they want to operate in a voltage output mode, and how many channels they want to operate in a current output mode, depending on their individual requirements.

Abrégé

The present disclosure relates to an integrated circuit with at least a first channel and a second channel. Each channel includes at least a DAC. The integrated circuit also includes a number of circuit elements interconnected between the channels. The circuit elements can be changed between a short circuit state and an open circuit state. Normally, each channel will operate independently of one another, using only the circuit components in its respective channel. However, the circuit elements are arranged to allow a user to combine part of the second channel with the first channel to improve the functionality and performance of the first channel. In particular, a state of the circuit elements can be chosen to combine components of the second channel with the first channel. For example, components (e.g. a sub-stage) of the second channel can be connected in parallel with corresponding components (e.g. a corresponding sub-stage) of the first channel. This may reduce the number of available channels, since the second channel can no longer be used as an independent channel. However, the performance of the first channel is enhanced. The presence of the circuit elements allow an end user to decide whether to sacrifice channel count for performance enhancements. For example, the user can provide user input to the integrated circuit to select how the channels are interconnected. Moreover, the integrated circuit does not use additional redundant circuitry to improve the first channel, and rather takes components from the second channel. As such, the integrated circuit can have a reduced size.

Abrégé

Chopping techniques that suppress fold-back into the signal band and spreads the offset across the spectrum are described. By using various techniques, chopping may be performed with a variable frequency clock to spread the offset across the signal spectrum. Spreading the offset across the signal spectrum means that there are no longer large spurious tones at a few frequencies.

Abrégé

A first predictor trained on observations within a training window of a time-series signal is obtained. A confidence envelope for a prediction window of the time-series signal is estimated using the first predictor. An outlier portion is identified within the prediction window and a deviation point for the outlier portion is determined. The training window is moved such that the training window ends proximate the deviation point. A second predictor is trained on observations within the training window of the time-series signal that has been moved according to the update process
