A semiconductor substrate includes a pair of trenches filled with a dielectric material. Dopant introduced into the mesa between the trenches is limited from diffusing laterally when the substrate is subjected to thermal processing. Therefore, semiconductor devices can be spaced more closely together on the substrate, and the packing density of the devices can be increased. Also trench constrained doped region diffuse faster and deeper than unconstrained diffusions, thereby reducing the time and temperature needed to complete a desired depth diffusion. The technique may be used for semiconductor devices such as bipolar transistors as well as isolation regions that electrically isolate the devices from each other. In one group of embodiments, a buried layer is formed at an interface between an epitaxial layer and a substrate, at a location generally below the dopant in the mesa. When the substrate is subjected to thermal processing, the buried layer diffuses upward, the dopant in the mesa diffuses downward until the two dopants merge to form an isolation region or a sinker extending downward from the surface of the epitaxial layer to the buried layer. In another embodiment, dopant is implanted between dielectrically filled trenches at a high energy up to several MeV, then diffused, combining the benefits of deep implantation and trenched constrained diffusion to achive deep diffusions with a minimal thermal budget.

In a first aspect, arbitrary shaping of the temporal envelope of noise is provided in spectral domain coding systems without the need of side-information. In the encoding, a filtered measure of quantization error is applied as a feedback signal to the frequency-domain representation of a discrete time-domain signal prior to quantization, so that the filtering parameters of said filtering affect the shaping of quantization noise in the time domain of the quantized frequency-domain representation of the discrete time-domain signal when it is inversely transformed from the frequency domain back to the time domain in decoding. This may be accomplished with respect to each of a plurality of frequency bins or groups of bins. In another aspect, frequency-domain noise-feedback quantizing in digital audio encoding is provided.

A multiplicity of synchronized inverters for driving a multiplicity of loads such as CCFLs that require high ac voltages are arranged in close proximity of the respective loads and controlled in phase. A frequency determination capacitor and a frequency determination resistor are connected to one of the inverters to generate a triangular wave signal and a clock signal. The triangular wave signal and clock signal thus generated are supplied to other inverters to synchronize all the loads so that they can be controlled in phase. The resistance of the frequency determination resistor is set to a substantially small magnitude at the time of startup to increase the frequency of the triangular wave signal, thereby enabling quick startup of the loads.

Systems for monitoring, storage, and analysis of information in signaling messages, communicated from originating networks to a destination network through one or more intermediate networks are described. Correlation and comparison between signaling messages of interest sent from an origination network to signaling messages received by the destination network allows for the detection of inconsistent information, e.g., information fields in a communicated message that have been altered, either intentionally or unintentionally, by an intermediate carrier. The introduction of an additional communications path over which notification messages are forwarded from signaling monitoring equipment in the origination network to signaling monitoring equipment in the destination network allows for a significant reduction in the memory storage requirements at the destination network and in the amount of processing required to match, compare, and evaluate signaling messages. In addition, the reduction in stored messages and processing time allows the monitoring system to operate in near-real time allowing for fraud detection while a call is still in progress.

A digital PLL circuit for providing as an output a clock signal having a frequency obtained by multiplying the frequency of a reference signal by a frequency control word (frequency ratio). In the digital PLL circuit, an RPA circuit (101) sequentially adds frequency control words (FCW) each having a decimal component. An output from the RPA circuit (101) is supplied to a micro-phase-error generator (107), which generates, based on the decimal part of the sequentially added value of the frequency control words (FCW), a plurality of threshold values in the vicinity of the actual amplitude value of a reference signal (REF), and which then calculates, based on these threshold values, an amplitude value of the reference signal (REF) and also calculates a phase error of the reference signal (REF) in accordance with the calculated amplitude value, and which further calculates a micro-phase-error between the reference signal (REF) and an output clock (CKV1). Thus, even if the frequency control words include decimal components, the residual micro-phase-error between the reference signal and the output clock can be calculated and corrected in a smaller area and with a less power consumption.
