Calibrating A Digital-To-Analog Converter

View page
US Patent:
7443323, Oct 28, 2008
Filed:
Jan 10, 2007
Appl. No.:
11/651858
Inventors:
Christian J. Rotchford - Austin TX, US
Brandt Braswell - Chandler AZ, US
Jiangbo Gan - Gilbert AZ, US
Michael L. Gomez - Tempe AZ, US
Gerald P. Miaille - Chandler AZ, US
Boris V. Razmyslovitch - Chandler AZ, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H03M 1/10
US Classification:
341120, 341118, 341144, 341145
Abstract:
Methods and corresponding systems for calibrating a digital-to-analog converter include selecting first and second code regions in the digital-to-analog converter, wherein the first and second code regions are separated by a boundary. Thereafter a waveform sequence is input into the digital-to-analog converter, wherein the waveform sequence has a zero offset at the boundary. Then a relative compensation value between the first and second code regions is adjusted to reduce a distortion in an output of the digital-to-analog converter. A magnitude of a third harmonic distortion of the waveform sequence can be used to measure distortion in the output. Adjusting the relative compensation can include converting the output of the digital-to-analog converter to a digital sequence, filtering the digital sequence, and measuring a harmonic distortion in the digital sequence.

US Patent:
8026080, Sep 27, 2011
Filed:
Mar 15, 2007
Appl. No.:
11/725040
Inventors:
Xiaobo Wang - San Diego CA, US
Yama A. Abassi - San Diego CA, US
Xiao Xu - San Diego CA, US
Jiangbo Gan - San Diego CA, US
Assignee:
Acea Biosciences, Inc. - San Diego CA
International Classification:
C12Q 1/20
C12Q 1/08
C12M 1/34
US Classification:
435 33, 435 40, 4352871, 4352884
Abstract:
The present invention includes devices, systems, and methods for assaying cells using cell-substrate impedance monitoring. In one aspect, the invention provides cell-substrate impedance monitoring devices that comprise electrode arrays on a nonconducting substrate, in which each of the arrays has an approximately uniform electrode resistance across the entire array. In another aspect, the invention provides cell-substrate monitoring systems comprising one or more cell-substrate monitoring devices comprising multiple wells each having an electrode array, an impedance analyzer, a device station that connects arrays of individual wells to the impedance analyzer, and software for controlling the device station and impedance analyzer. In another aspect, the invention provides cellular assays that use impedance monitoring to detect changes in cell behavior or state. In some preferred aspects, the assays are designed to investigate the affects of compounds on cells, such as cytotoxicity assays.

US Patent:
8068797, Nov 29, 2011
Filed:
Oct 10, 2008
Appl. No.:
12/249649
Inventors:
Jiangbo Gan - Gilbert AZ, US
Srinivasa R. Bommareddy - Gilbert AZ, US
Pravin Premakanthan - Chandler AZ, US
Assignee:
Freescale Semiconductor, Inc. - Austin TX
International Classification:
H04B 1/04
H04K 3/00
US Classification:
4551143, 455126, 4551271, 375296
Abstract:
A gain control process () executed at a transmitter () generates () a gain ramp signal () having a delay component () and a gain component (). The process () further generates () and incorporates () a gain arc () into a digital signal to form a digital gain signal () having a digital gain change (). A combiner () combines a digital input signal () with the digital gain signal () to generate a pre-compensated digital signal (). A variable gain amplifier () applies a sequence of gains () in the gain component () of the gain ramp signal () to a pre-adjusted analog signal () in order to generate a gain-adjusted analog signal (). Application of the gain component () and the digital gain change () occurs when a portion () of the gain arc () indicates a low instantaneous signal power at an antenna () in order to reduce ACLR degradation.
