Abstract: Embodiments relate to intelligent tire systems and methods. In an embodiment, a sensor module mounted in a tire includes a sensor configured to generate sensor data related to a condition of the tire; and a transceiver communicatively coupled to the sensor and configured to communicate with another in-tire sensor module and with a control unit external to the tire.

Abstract: The invention is related to intelligent tire systems and methods. In one embodiment, an intelligent tire system (ITS) comprises a first sensor device, a second sensor device, a central control unit, and a transceiver. The first sensor device is mounted in a tire of a vehicle and comprises a radio frequency (RF) transmitter. The second sensor device is mounted in the tire and comprises an RF transceiver, the second sensor device adapted to receive a transmitter transmission from the first sensor device comprising first sensor data. The central control unit is mounted in the vehicle. The transceiver is mounted in the vehicle and is adapted to receive a transceiver transmission from the second sensor device comprising first sensor data and second sensor data and to transmit the transceiver transmission to the central control unit.

Abstract: A current mirror arrangement comprising two transistors (11, 12) which are of different conductivity types and are each suitable for outputting a bias current (PBIAS, NBIAS) is specified. A controlled current source (13, 13?) is connected between the two transistors (11, 12) and forms the output of a current mirror (18, 13?). The proposed principle ensures that the output bias signals (PBIAS, NBIAS) match one another in a highly precise manner. The proposed current mirror arrangement may preferably be integrated using CMOS circuit technology.

Abstract: A current mirror arrangement is specified in which two current mirror transistors (2, 3) form a current mirror. Two cascode transistors (11, 12) are connected up to the two current mirror transistors (2, 3) to form a cascode stage. The cascode transistors (11, 12) in each case comprise a plurality of partial transistors (13, 14, 15; 16, 17, 18) connected up to one another in series with respect to their controlled paths. As a result it is possible to connect the connecting node of the current mirror transistors to a connecting node between two partial transistors (14, 15). This in turn brings about an increase in the input voltage range for a current source (4) that provides an input current for the current mirror.
