Abstract:
A temperature sensor device and method of sensing temperature are disclosed. The device and method include generating a reference voltage inversely correlated to the temperature, generating a plurality of analysis voltages correlated to the temperature using a reference current, comparing the reference voltage to each of the plurality of analysis voltages, and generating a temperature estimate based on the comparison. The device and method may also include a method to selectively bypass various resistors in a resistor stack used to generate the various analysis voltages. Another embodiment of the present invention comprises a semiconductor device including at least one temperature sensor according to the invention described herein. The temperature sensor and method of sensing temperature may be incorporated into a semiconductor device, which may be fabricated on a semiconductor wafer and included in an electronic system.

Abstract:
A dynamic channel allocation method and system for use in a wireless network operates by monitoring at least the allocated channel allocated to a particular network node to generate one or more channel metrics relating to radio conditions on the channel. The metrics generated are Received signal power, signal to noise ratio of transmissions on the network and long-term mean square of the equaliser error used in each terminal. The generated metrics are communicated back to the cell access point or the network control server over a signalling channel, and a new frequency is allocated to the cell if it is determined from the metrics that the presently allocated channel is suffering interference. The signalling channel is preferably an ATM VPI/VCI pair, such that signalling messages are transmitted as ATM cells which can be communicated across the wireless channel using the sane signalling frame as is used for payload cells.
