Flicker Noise Degeneration Technique For Vco

US Patent:
7486154, Feb 3, 2009
Filed:
Oct 30, 2006
Appl. No.:
11/590073
Inventors:
Chun Geik Tan - Singapore, SG
Randy Tsang - Foster City CA, US
Assignee:
Marvell International Ltd.
International Classification:
H03L 1/00
US Classification:
331186, 331 36 C, 331117 FE
Abstract:
An oscillating circuit having improved noise degeneration includes an oscillator and a noise degeneration circuit. The oscillator is adapted to provide a differential oscillating signal between first and second output terminals, and includes first and second transistors in communication with the first and second output terminals. The noise degeneration circuit includes cross-coupled capacitors and cross-coupled third and fourth transistors operated in a linear region. The noise degeneration circuit reduces the low frequency gm of the first and second transistors to lower the effect of flicker noise. At relatively high frequencies, the capacitors provide a virtual AC ground to the source terminals of the first and second transistors. The noise degeneration circuit receives a voltage signal from a biasing circuit adapted to track variations in electrical characteristics of the third and fourth transistors.

11/489835
Inventors:
Chun Geik Tan - Singapore, SG
Randy Tsang - Foster City CA, US
Yonghua Song - Cupertino CA, US
Assignee:
Marvell International Ltd.
International Classification:
H03B 5/08
US Classification:
331 36C, 331177 V
Abstract:
A capacitor bank adapted to provide a variable capacitance to an electronic circuit is provided. The capacitor bank has at least a most significant bit and a least significant bit and includes a first capacitor cell having a first capacitance value and disposed between a first node and a second node, thereby forming the most significant bit. The capacitor bank also includes a second capacitor cell having a second capacitance value and disposed between the first node and the second node, thereby forming the least significant bit. The second capacitance value is less than the first capacitance value. Additionally, the second capacitor cell includes a first T-network capacitor unit in electrical communication with a source of a transistor and a second T-network capacitor unit in electrical communication with a drain of the transistor.

Voltage Control Oscillator Noise Reduction Technique And Method Thereof

US Patent:
6727736, Apr 27, 2004
Filed:
Aug 23, 2002
Appl. No.:
10/226549
Inventors:
Randy Tsang - Foster City CA
Shuran Wei - San Jose CA
Assignee:
Marvell International, Ltd. - Hamilton
International Classification:
H03L 406
US Classification:
327157, 327156
Abstract:
A phase locked loop including a loop filter to generate a control voltage as a function of an input signal and a. reference voltage. A voltage controlled oscillator (VCO) coupled to the loop filter, includes a varactor having terminals. In response to the control voltage, the VCO generates a periodic output signal having a frequency that is a function of the varactor and the control voltage. The VCO duplicates noise appearing on one of the varactor terminals to another of the varactor terminals so that noise in the periodic output signal is reduced.

Adaptive Channel Bandwidth Selection For Mimo Wireless Systems

US Patent:
7545867, Jun 9, 2009
Filed:
Dec 23, 2003
Appl. No.:
10/743941
Inventors:
Hui-Ling Lou - Palo Alto CA, US
Randy Tsang - Foster City CA, US
Assignee:
Marvell International, Ltd. - Hamilton
International Classification:
H04L 27/00
US Classification:
375259
Abstract:
A wireless communications device for a multiple input multiple output wireless communications system includes a radio frequency transceiver that includes at least two antennae and a medium access control device that includes a link adaptation module. The link adaptation module dynamically adjusts a bandwidth of the wireless communications device based on a transmission error rate and a correlation measurement at a remote wireless communications device. A transmission error module receives the transmission error rate from the remote wireless communications device and generates a transmission error control signal. A signal correlation module receives the correlation measurement from the remote wireless communication device and generates a signal correlation control signal. The link adaptation module adjusts at least one of the bandwidth and an amount of spatial multiplexing that is executed by a space-time processor based on the transmission error control signal and the signal correlation control signal.

Self Biased Low Noise High Psrr Constant Gm For Vco

US Patent:
7667533, Feb 23, 2010
Filed:
Oct 24, 2006
Appl. No.:
11/586393
Inventors:
Chun-Geik Tan - Singapore, SG
Randy Tsang - Foster City CA, US
Yonghua Song - Cupertino CA, US
Assignee:
Marvell International Ltd.
International Classification:
G05F 1/10
US Classification:
327541, 327538, 327543
Abstract:
A system and method for voltage controlled oscillator (VCO) biasing in low voltage circuits including low resistance elements that are especially susceptible to noise. In one embodiment, a poly resistor and triode resistor is used to cancel or offset the effects that temperature variations have on the circuit. The triode resistor is powered by a voltage source that uses a pair of diodes coupled to a constant transconductance (gm) circuit to generate a reduced noise voltage that is independent of the power supply noise. The size of the triode resistor and poly resistors can be varied.

Appl. No.:
12/247869
Inventors:
David Cousinard - Morges, CH
Philippe Mosch - Le Mont-sur-Lausanne, CH
Lydi Smaini - St. Julien en Genevois, FR
Randy Tsang - Foster City CA, US
Cao-Thong Tu - Lausanne, CH
Miljan Vuletic - Lausanne, CH
Assignee:
Marvell International Ltd. - Hamilton
International Classification:
H03C 3/00
H03C 3/06
H03L 7/06
H04B 1/04
US Classification:
332127, 331 23, 455113
Abstract:
Circuits and methods for frequency modulation (FM) using a digital frequency-locked loop (DFLL). A digitally controlled oscillator (DCO) generates and adjusts a frequency of a modulated signal based on a digital tuning word. A DFLL control logic circuit receives a feedback of the modulated signal and generates a carrier signal word. A sigma delta modulator circuit receives an input signal and applies dithering to produce a dithered input signal word. An adder circuit receives and sums the dithered input signal word and the carrier signal word to produce the digital tuning word. The DFLL control logic circuit adjusts the carrier signal word to lock a carrier frequency of the modulated signal.
