An integrated circuit device comprises at least one non-linear circuit. Further the integrated circuit device comprises a plurality of terminal circuits coupled to the non-linear circuit. Each terminal circuit comprises an associated terminal and an inductor coupled to the associated terminal and to the at least one non-linear circuit. A protective device for protection of a circuit, comprises an electro-static discharge protection element configured to be coupled to a circuit terminal and an inductor coupled to the electro-static discharge protection element and configured to be coupled to the circuit. The inductor has a low quality factor.

Integrated circuit device and a device for protection of a circuit

A MEMS sensor device includes an electrically conductive membrane and an electrically conductive closed loop structure. The closed loop structure is arranged in proximity to the membrane and is configured to reduce eddy currents in the membrane.

Micro-electro-mechanical system sensor devices

An LED controller and a method for controlling an LED device is disclosed. A current sense signal is representative of a load current flowing through the LED device. The current sense signal is compared with an upper threshold value and a lower threshold value. Current is provided to the LED device via an inductor coupled in series with the LED device when the current sense signal exceeds the upper threshold. A load current loop is closed over a free-wheeling diode when no current is provided to the LED device while the current sense signal is below the lower threshold. The upper threshold and the lower threshold are adjusted dependent on the current sense signal such that peak values of the current sense signal match corresponding desired peak values.
