Abstract: A device comprises a magnet and an angle sensor, wherein the angle sensor is configured to detect a rotation angle of the magnet. The device also contains a rotation counter, wherein the rotation counter is configured to record a number of rotations of the magnet. The angle sensor and the rotation counter are implemented in physically separate components.

Abstract: A gray zone prevention circuit includes: a first gain stage circuit including a first input terminal and a first output terminal, the first gain stage circuit amplifies a feedback signal received at the first input terminal and generates an amplified signal at the first output terminal; a second gain stage circuit including a terminal that is coupled to the first output terminal for receiving the amplified signal and a second output terminal, where the second gain stage circuit is configured to generate a monitored signal based on the amplified signal; a feedback circuit coupled between the second output terminal and the first input terminal and configured to convert the monitored signal into the feedback signal; and a comparator circuit including a monitoring node coupled to the first output terminal for receiving the amplified signal, wherein the comparator circuit is configured to monitor the monitored signal indirectly via the amplified signal.

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.
