Abstract: In an example embodiment, a system detects the degree of rotation of a knob, the system comprises a shaft having a length and a first end and a second end; the second end has an oblique reflective surface defined thereon; the first end fixedly attached to the knob. Containing the shaft is a rotation body, having a receptacle to accommodate the second end of the shaft with the oblique reflective surface exposed. An integrated circuit optical module is optically coupled the rotation body and the optical module detects light irradiance profile from the oblique reflective surface. The optical module includes a solid state light source and a plurality of photo detectors which generate an electrical signal upon exposure to light. As the knob is rotated, the oblique reflective surface generates a changing asymmetric irradiance profile, the change being translated into an electrical signal via the photo detectors. The electrical signal corresponds to the degree of rotation of the knob.

Abstract: A sensor for contactlessly detecting currents, has a sensor element having a magnetic tunnel junction (MTJ), and detection circuitry, the sensor element having a resistance which varies with the magnetic field, and the detection circuitry is arranged to detect a tunnel current flowing through the tunnel junction. The sensor element may share an MTJ stack with memory elements. Also it can provide easy integration with next generation CMOS processes, including MRAM technology, be more compact, and use less power. Solutions for increasing sensitivity of the sensor, such as providing a flux concentrator, and for generating higher magnetic fields with a same current, such as forming L-shaped conductor elements, are given. The greater sensitivity enables less post processing to be used, to save power for applications such as mobile devices. Applications include current sensors, built-in current sensors, and IDDQ and IDDT testing, even for next generation CMOS processes.
