Patent Number Title Of Patent Date Issued
6570226 Device and circuit for electrostatic discharge and overvoltage protection applications May 27, 2003
The present invention is related to a semiconductor device for electrostatic discharge or overvoltage protection applications, said device comprising means for absorbing an electrostatic discharge pulse or an overvoltage level, said means being triggered at intermediate voltages and
6538986 Data transmission system and method using nQAM constellation with a control channel superimposed March 25, 2003
A transmission system using nQAM. A control channel is superimposed on a nQAM data channel. It is desirable to separate control channel data from user data without using a higher level protocol layer. In multi-carrier systems with variable bit-loading it is particularly desirable that th
6493395 Multi-carrier transmission systems December 10, 2002
A multi-carrier transmission system using orthogonal carriers with high order QAM constellations for the transmission of multiple bits per carrier and symbol. Such systems place high demands on the synchronization of the receiver with the transmitter. The maximum permitted deviation from
6466629 Multi-carrier transmission systems October 15, 2002
A multi-carrier transmission system. A received multi-carrier signal is sampled and digitized before FFT processing. Multi-carrier signals consist of many narrow band carrier waves which convey data via a wide band channel. The amplitude distribution of the sum of all the individual
6456649 Multi-carrier transmission systems September 24, 2002
A multi-carrier transmission system such as a DMT system. Channel information is transmitted between two transceivers using a plurality of sub-carriers modulated with symbols, each of which represents a multiplicity of bits. Each of the transceivers includes a receiver and a transmit
6438174 Multi-carrier transmission systems August 20, 2002
A multi-carrier transmission system such as a DMT based VDSL system. The system uses orthogonal carriers with high order QAM constellations for the transmission of multiple bits per carrier and symbol. This estimate includes digital receiver and transmitter units with the receiver unit
6366554 Multi-carrier transmission systems April 2, 2002
A multi-carrier transmission system, for example a DMT system. Channel information is transmitted between two transceivers using a plurality of subcarriers. Each subcarrier, or symbol, has a parameter associated with it. The transceivers are adapted to transmit the channel information as
6363128 Multi-carrier transmission systems March 26, 2002
A multi-carrier transmission system, such as a DMT system. A receiver must be able to recover a sampling clock that is very accurately synchronized to a transmitter sampling clock. Typically, synchronization is achieved by using a reserved carrier, the pilot carrier, which is transmitted
6359926 Multi-carrier transmission systems March 19, 2002
A two-way multi-carrier transmission system, such as a DMT system. If there are dynamic changes in the transmission parameters, synchronization must be maintained between the transmitter and the receiver when the transmission parameters changed. The first stage of such a process requ
6320903 Multi-carrier transmission systems November 20, 2001
A multi-carrier transmission system using orthogonal carriers with high order QAM constellations for the transmission of a plurality of bits per carrier and symbol. The system uses some method for the determination of an inverse channel model to be used in the equalization process. In th
6288658 Antisaturation system for an analog-to-digital converter September 11, 2001
A digital signal processing system, including an analog-to-digital converter adapted to provide at least n-bit samples to a processor, and range selection circuitry for stepwise adjusting the range of the analog-to-digital converter to the amplitude of an input signal and for shiftin
6169456 Auto-biasing circuit for current mirrors January 2, 2001
In accordance with the present invention, an auto-biased cascode current circuit capable of improved range in headroom is disclosed. In one embodiment, the current circuit includes a current mirror and a bias circuit, where the current mirror contains a reference leg and an output le
