Patent number: 9001848Abstract: A code-division multiplexing (CDM) system utilized in multi-channel (MC) front-end integrated circuits to significantly reduce the power consumption of such systems. The CDM system extends data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity. Systems and methods permit architects to fabricate MC integrated circuits with ultra low power consumption and small chip area. Another embodiment relates to the system's compressor organizing samples of the input signal in such a way that the downstream analog-to-digital converter quantizes the higher variance samples with a higher resolution compared to the resolution it uses to quantize other samples with lower variance.Type: GrantFiled: November 27, 2012Date of Patent: April 7, 2015Assignee: The Regents of the University of CaliforniaInventors: Fred Tzeng, Payam Heydari

Patent number: 8320408Abstract: A challenging problem is maintaining low power consumption in multi-channel (MC) systems, where multiple input signals demand several front-end analog signal-processing blocks to be replicated. A code-division multiplexing (CDM) system can be generalized as a signal compression-decompression involving an analog-to-digital converter (ADC). This invention utilizes CDM in MC front-end integrated circuits to significantly reduce the power consumption of such systems. The invention also extends CDM's data compression advantages to uncorrelated and weakly correlated MC signals through the introduction of a new Multi-Channel Signal Binning and Multiplexing (MCSBM) method and architecture. The proposed method achieves significant reductions in power consumption in comparison to a conventional time-division multiplexing quantizer, while adding only a modest amount of overhead and complexity.Type: GrantFiled: January 27, 2010Date of Patent: November 27, 2012Assignee: The Regents of the University of CaliforniaInventors: Fred Tzeng, Payam Heydari

Patent number: 8265118Abstract: Described herein are code-modulated multi-signal systems. In one embodiment, a multi-signal system receives multiple input signals and code-modulates each input signal with a unique code to distinguish the input signal from the other input signals. The input signals may come from multiple antennas, multiple sensors, multiple channels, etc. The code-modulated signals are then combined into a combined signal that is sent through shared blocks and/or transmitted across a shared medium in a shared path. After shared processing and/or shared transmission, the individual signals are recovered using matched filters. Each matched filter contains a code corresponding to one of the unique codes for recovering the corresponding signal from the combined signal. The recovered signals may then be inputted to additional processors for further processing.Type: GrantFiled: March 3, 2008Date of Patent: September 11, 2012Assignee: The Regents of the University of CaliforniaInventors: Fred Tzeng, Amin Jahanian, Payam Heydari

Patent number: 7622989Abstract: Described herein are multi-band LNAs that reuse inductors for different frequency bands to minimize chip area. In an embodiment, a multi-band LNA is capable of operating in a narrowband (NB) and a wideband (WB) while reusing at least one input impedance matching inductor and at least one load inductor for both bands. The reuse of inductors results in a more efficient use of chip area. In an exemplary embodiment, the LNA comprises a common source transistor and a common gate transistor. In this embodiment, the LNA operates in a common source configuration using the common source transistor to amplify input signals in the NB, and operates in a common gate configuration using the common gate transistor to amplify input signals in the WB. The LNA reuses an input impedance matching inductor and a load inductor in both configurations, and thus both bands.Type: GrantFiled: April 22, 2008Date of Patent: November 24, 2009Assignee: The Regents of the University of CaliforniaInventors: Fred Tzeng, Amin Jahanian, Payam Heydari
