Frequency Synthesizer With Digitally-Controlled Oscillator
view source
US Patent:

6734741, May 11, 2004
Filed:

Nov 30, 2001
Appl. No.:

10/006607
Inventors:

Robert B. Staszewski - Garland TX
Dirk Leipold - Plano TX
Khurram Muhammad - Richardson TX
Chih-Ming Hung - McKinney TX
Assignee:

Texas Instruments Incorporated - Dallas TX
International Classification:

H03L 700
US Classification:

331 36C, 331117 R, 375376
Abstract:

A transmitter ( ) based on a frequency synthesizer includes an LC tank ( ) of a digitally controlled oscillator (DCO) with various arrays of capacitors. The LC tank is divided into two major groups that reflect two general operational modes: acquisition and tracking. The first group (process/voltage/temperature and acquisition) approximately sets the desired center frequency of oscillation initially, while the second group (integer and fractional tracking) precisely controls the oscillating frequency during the actual operation. For highly accurate outputs, dynamic element matching (DEM) is used in the integer tracking controller to reduce non-linearities caused by non-uniform capacitor values. Also, a preferred range of the integer tracking capacitor array may be used for modulation after the selected channel has been acquired. A digital sigma-delta modulator circuit ( ) drives a capacitor array ( ) in response to the fractional bits of the error word.

Active Removal Of Aliasing Frequencies In A Decimating Structure By Changing A Decimation Ratio In Time And Space
view source
US Patent:

6856925, Feb 15, 2005
Filed:

Oct 11, 2002
Appl. No.:

10/269349
Inventors:

Khurram Muhammad - Richardson TX, US
Robert B. Staszewski - Garland TX, US
Gennady Feygin - Dallas TX, US
Assignee:

Texas Instruments Incorporated - Dallas TX
International Classification:

G06F019/00
US Classification:

702 75, 455296
Abstract:

When a sample stream is decimated, frequency components from outside of a desired frequency band are aliased into the desired band, causing interference and loss of information. Different decimating ratios result in different frequencies aliasing into the desired frequency band. A current-mode sampling mixer with capacitor banks and that are controlled by a digital control unit with a capability to integrate and decimate an RF current at different decimating ratios is able to measure the frequency spectrum with different decimating ratios. The measured frequency spectrum is then analyzed to detect the presence of interferers aliased into the desired frequency band. The interferers can then be eliminated or avoided.

Subsampling Communication Receiver Architecture With Relaxed Ifa Readout Timing

US Patent:

6963732, Nov 8, 2005
Filed:

Apr 25, 2002
Appl. No.:

10/132436
Inventors:

Khurram Muhammad - Richardson TX, US
Dirk Leipold - Plano TX, US
Assignee:

Texas Instruments Incorporated - Dallas TX
International Classification:

H04B001/00
US Classification:

455131, 455137, 455323
Abstract:

A first periodic voltage waveform () is downconverted into a second periodic voltage waveform (). A plurality of temporally distinct samples (SA, SA,. . . ) respectively indicative of areas under corresponding fractional-cycles of the first voltage waveform are obtained. The samples are combined to produce the second voltage waveform, and are also manipulated to implement a filtering operation such that the second voltage waveform represents a downconverted, filtered version of the first voltage waveform. The second waveform is driven by an amplifier stage (), and the second waveform can be advantageously constructed so as to permit the amplifier stage to perform internal resets, offset corrections and other ancillary amplifier stage adjustments without losing information in the first waveform.

Subsampling Communication Receiver Architecture With Gain Control And Rssi Generation

US Patent:

7003276, Feb 21, 2006
Filed:

Apr 25, 2002
Appl. No.:

10/132025
Inventors:

Khurram Muhammad - Dallas TX, US
Dirk Leipold - Plano TX, US
Kenneth J. Maggio - Dallas TX, US
Assignee:

Texas Instruments Incorporated - Dallas TX
International Classification:

H04B 1/26
US Classification:

455323, 455313, 455334
Abstract:

A first periodic voltage waveform () is downconverted into a second periodic voltage waveform (). A plurality of temporally distinct samples (SA, SA,. . . ) respectively indicative of areas under corresponding fractional-cycles of the first voltage waveform are obtained. The samples are combined to produce the second voltage waveform. The samples can be manipulated to provide gain adjustment to the second voltage waveform. The samples are obtained by charging a sampling capacitance in response to a current waveform that corresponds to the first voltage waveform. The use of different sampling capacitances during respective predetermined time intervals permits the signal strength of the first waveform to be determined from observation of the second waveform.

US Patent:

7006813, Feb 28, 2006
Filed:

May 16, 2002
Appl. No.:

10/147784
Inventors:

Robert B. Staszewski - Garland TX, US
Khurram Muhammad - Dallas TX, US
Chih-Ming Hung - McKinney TX, US
Dirk Leipold - Plano TX, US
Assignee:

Texas Instruments Incorporated - Dallas TX
International Classification:

H04B 1/26
US Classification:

455323, 455313, 455324, 323281
Abstract:

The application of a non-zero voltage offset to rotating capacitors and permit the use of a single positive voltage supply. However, the precharging of the rotating capacitors and is power inefficient. A power efficient and low-noise precharging operation is realized through the sharing of the charge on a feedback capacitor and that is significantly larger than the rotating capacitors Once a precharging operation is complete, the charge on the feedback capacitor and is refreshed from its residual charge level (rather than zero charge level) to a desired charge level.
