A swapping unit that swaps the first signal processing unit between the first sensor output and first system output to the second sensor output and second system output and simultaneously swaps the second signal processing unit from the second sensor output and second system output to the first sensor output and first system output and vice versa. A method for detecting errors in a position sensor system is also presented.

Abstract: In a cellular communications network including user equipment and an access network, a cell-blocking method involves designating a cell in the network that is to be blocked and activating a cell-blocking operating mode of a node of the access network of the cellular communications network. According to the cell-blocking method, upon activation of the cell-blocking mode of the access-network node, active calls in the designated cell are detected and disconnected. The disconnection of active calls may be performed selectively based on an access class or establishment cause associated with the call. The cell-blocking may be hidden because the access-network node may not broadcast any data that is indicative of cell-blocking and, when a user equipment in the affected cell attempts to set-up a call, the access-network node may reject the call using an admission control mechanism or may send back a spoofed message from the core network.

Abstract: An electronic device includes an operational amplifier, with the operational amplifier having an amplifier input stage coupled with a first output node to an amplifier output stage. A compensation capacitance is connected between an output node of the amplifier output stage and the first output node of the amplifier input stage, thereby operating as a compensator for stabilizing the operational amplifier. The compensation capacitance provides a parasitic diode drawing a first leakage current from the first output node of the amplifier input stage, a leakage current compensation circuit being coupled to the first output node of the amplifier input stage and coupled to a second output node of the amplifier input stage for drawing a first current from the first output node and a second current from the second output node. The leakage current compensation circuit is adapted such that the second current is greater than the first current by an amount corresponding to the first leakage current.

The output transistor in the output stage has a coupling path between its control input and its controlled path. The coupling path comprises a series circuit comprising a Miller compensation capacitance and a resistance with a controllable resistance value. It is thus possible to ensure stable operation of the amplifier regardless of bias and load conditions while simultaneously reducing the quiescent current drawn.
