Abstract: An improved die seal ring is described which includes at least one break. In the region of the break in the die seal ring, the doping is modified so that the impedance of the electrical path across the break through the substrate is increased. Offsets in the break may also be used and the offset may be within a break in a track and/or between breaks in different tracks, where the die seal ring includes more than one track.

Abstract: A method of measuring a very low frequencycomponent of a signal is described. The method comprises sampling the signal at random timesto generate a "decimated" signal, and then filtering the decimated signal using a low-passfilter. There are many different methods which may be used to sample the signal at random times, and in one example, a sample of the signal may be taken and then passed to the low-passfilter with a probability of1/M, where M is the decimation factor.

Abstract: Methods of spectral partitioning which may be implemented in an encoder are described. The methods comprise determining an estimateof bit requirements for each of a plurality of spectral sub-bands. These estimates are then used to group the sub-bands into two or more regions by minimising a cost function. This cost function is based on the estimates ofbit requirements for each sub-band and the estimates may include estimates of code bit requirements and / or additional code bit requirements for each sub-band. These estimates may be determined in many different ways and a number of methods are described.
