Patent number: 9484981Abstract: Synchronous CDMA/spread spectrum methods, devices, and systems are used to suppress crosstalk in clock-forwarded on-chip interconnects. Transmitting a spread spectrum signal across on-chip interconnects for recovery at the terminus permit integrated chip designers to overcome the effects of capacitive cross-talk between adjacent data bus lines. The methods, devices, and systems provided herein improve cross-talk immunity between adjacent high speed signal lines by applying synchronous CDMA spread spectrum techniques to some or all of the high speed signal lines. Other methods, devices, and systems provided herein apply synchronous CDMA spread spectrum techniques to the concept of sending phantom signals to reduce the number of signal lines used to carry data.Type: GrantFiled: July 7, 2014Date of Patent: November 1, 2016Assignee: The Regents of the University of CaliforniaInventors: Tzu-Chien Hsueh, Sudhakar Pamarti

Patent number: 6515607Abstract: The present invention provides a delta-sigma-modulator for converting an external analog signal to a digital out-put signal. The delta-sigma modulator comprises a first filter circuit, a second filter circuit, a one-bit quantization, a multi-bit quantization, a digital-to-analog converter, and a digital filter. The first filter circuit outputs a first analog signal according to the external analog signal and an one-bit output signal. The second filter circuit outputs a third analog signal according to the first analog signal and a second analog signal. The one-bit quantization converts the third analog signal into the one-bit output signal. The multi-bit quantization converts the third analog signal into a multi-bit output signal. The digital-to-analog converter comprises a plurality of capacitors, and determines the number of capacitors to be charged according to the multi-bit output signal, then selects the capacitors to be charged in a predetermined turn and charges the capacitors.Type: GrantFiled: March 18, 2002Date of Patent: February 4, 2003Assignee: Archic Tech, Corp.Inventors: Shen-Iuan Liu, Chien-Hung Kuo, Tzu-Chien Hsueh, Hsiang-Hui Chang
