Abstract:
Embodiments feature a circuit that includes a first set of differential switches to generate a first mixer output. The first set includes source terminals, a differential input terminal, gate terminals, and first mixer output terminals. For the first set, the source terminals are coupled to the differential input terminal and the gate terminals are coupled to a first differential oscillator input. The circuit includes a second set of differential switches to generate a second mixer output. The second set of differential switches has source terminals, gate terminals, and second mixer output terminals. For the second set of differential switches, the source terminals of the second set of differential switches are coupled to the first mixer output terminals to receive the first mixer output and the gate terminals of the second set of differential switches are coupled to a second differential oscillator input. The second mixer output terminals couple a filter.

Digital Tuning Of Crystal Oscillators

US Patent:
7532079, May 12, 2009
Filed:
Jun 18, 2007
Appl. No.:
11/764701
Inventors:
David H. Shen - Saratoga CA, US
Ann P. Shen - Saratoga CA, US
Assignee:
NanoAmp Solutions, Inc. (Cayman) - Santa Clara CA
International Classification:
H03B 5/00
US Classification:
331116FE, 331175, 331179, 331116 R, 331177 V
Abstract:
Embodiments feature techniques and systems for digitally tuning a crystal oscillator circuit. In one aspect, embodiments feature a method for making a digitally tuned crystal oscillator circuit. The method involves receiving a multi-bit input signal into a digital modulator, modulating the multi-bit input signal with the digital modulator by oversampling or by noiseshaping and oversampling to produce a digitally-modulated output signal having a lower number of bits than the multi-bit input signal. The method also involves coupling a tuning capacitor with the crystal oscillator circuit, and coupling the digitally-modulated output signal from the digital modulator to the crystal oscillator circuit and the tuning capacitor. In some embodiments, the digital modulator can a delta-sigma modulator, a noiseshaping modulator, a delta modulator, a pulse width modulator, a differential modulator, or a continuous-slope delta modulator.

Phase-Locked Loop Start-Up Techniques

US Patent:
7639088, Dec 29, 2009
Filed:
Apr 25, 2008
Appl. No.:
12/110048
Inventors:
David H. Shen - San Jose CA, US
Ann P. Shen - Saratoga CA, US
Axel Schuur - Mountain View CA, US
Assignee:
NanoAmp Mobile, Inc. - Santa Clara CA
International Classification:
H03L 7/10
H03L 7/18
H04B 1/00
US Classification:
331 16, 331 18, 331 25, 455260
Abstract:
Implementations feature systems and techniques for phase-locked loops (PLLs). In some aspects, implementations feature a system that has a PLL circuit including an oscillator and programmable reference frequency divider circuit or a programmable feedback frequency divider circuit. The PLL includes a control circuit to reduce a time required for a PLL settling time by programming a division value into the programmable reference frequency divider circuit and/or the programmable feedback frequency divider circuit to target the oscillator to operate outside of a system operating frequency range of the oscillator during start-up of PLL operations. The control circuit can program another division value into the programmable reference frequency divider circuit and/or the programmable feedback frequency divider circuit after stabilization of the variable oscillator.

Crystal Oscillator Frequency Tuning Circuit

View page
US Patent:
7639092, Dec 29, 2009
Filed:
Aug 10, 2007
Appl. No.:
11/837042
Inventors:
David H. Shen - Saratoga CA, US
Ann P. Shen - Saratoga CA, US
Assignee:
NanoAmp Solutions Inc. (Cayman) - Santa Clara CA
International Classification:
H03B 5/36
US Classification:
331 36C, 331158, 331177 V
Abstract:
Embodiments feature techniques and systems for analog and digital tuning of crystal oscillators. In one aspect, some implementations feature a method for tuning a frequency of a crystal oscillator that can include adjusting the tuning frequency of the crystal oscillator from a nominal frequency via a switched-capacitor frequency tuning circuit, the switched-capacitor frequency tuning circuit can have switchable sections to adjust the tuning of the crystal oscillator. The method can include controlling an analog control input that is coupled to a varactor within each of the switchable sections, where each of the switchable sections can include a fixed capacitor in series with the varactor and a switch. The method can involve controlling a digital control input, where the digital control input can electrically connect or disconnect one or more of the switchable sections from the crystal. There can be independent control between the digital and analog tuning mechanisms.

Analog To Digital Converter

US Patent:
7646325, Jan 12, 2010
Filed:
Aug 7, 2008
Appl. No.:
12/187632
Inventors:
Axel Schuur - Mountain View CA, US
David H. Shen - San Jose CA, US
Ann P. Shen - Saratoga CA, US
Assignee:
NanoAmp Mobile, Inc. - Santa Clara CA
International Classification:
H03M 1/12
US Classification:
341172, 341122, 341143, 341150, 341155
Abstract:
An ADC, such as a CT SD-ADC, includes a clock generation circuit that produces charging and discharging clock signals such that a settling time for an integrator in the ADC is increased. The clock signals may control a feedback SD-DAC in the CT SD-ADC. The clock signals also may be asymmetric and/or may result in the settling time of the integrator being greater than half the system clock.

Load Inductor Sharing

US Patent:
7649416, Jan 19, 2010
Filed:
Sep 23, 2008
Appl. No.:
12/236344
Inventors:
David H. Shen - San Jose CA, US
James Burnham - Sunnyvale CA, US
Ali Tabatabaei - San Francisco CA, US
Ann P. Shen - Saratoga CA, US
Assignee:
NanoAmp Mobile, Inc. - Santa Clara CA

Techniques For Passive Subharmonic Mixing

View page
US Patent:
7657246, Feb 2, 2010
Filed:
Jun 15, 2007
Appl. No.:
11/764095
Inventors:
David H. Shen - Saratoga CA, US
Ann P. Shen - Saratoga CA, US
Assignee:
NanoAmp Mobile, Inc. - Santa Clara CA
International Classification:
H04B 1/28
US Classification:
455318, 455333
Abstract:
Particular embodiments of mixer designs permit greater integration on standard chips with an improvement in power and linearity to enable low-power, high-performance reception. Some embodiments feature a method of frequency conversion using at least two stages of switches to mix an input signal with reference signals. The method involves mixing a differential input signal with a first differential reference signal through a first stage of switches, generating from the first stage of switches a first frequency converted differential signal, and mixing the first frequency converted differential signal with a second differential reference signal through a second stage of switches. The method includes generating from the second stage of switches a second frequency converted differential signal. The first differential reference signal can be phase shifted from the second differential reference signal and can have a different frequency. The mixer designs can have multiple stages of switches in a low-supply voltage design.
