Filed:

Jul 30, 2004

Appl. No.:

10/902465

Inventors:

Steven Jaffe - Irvine CA, US
Donald McMullin - Laguna Hills CA, US
Ramon Gomez - San Juan Capistrano CA, US

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03L 7/00
H03B 21/00
H03B 27/00

US Classification:

331 18, 331 45, 327105, 327106

Abstract:

An apparatus provides a local oscillator signal based on a selected channel of an RF input signal. For example, the apparatus can set a frequency of the local oscillator signal based on the selected channel. Digital circuitry can be used to generate the local oscillator signal. For instance, the digital circuitry can provide a digital representation of the local oscillator signal. A DAC can convert the digital representation to an analog signal. Other circuitry can provide first and second quadrature components of the local oscillator signal, based on the analog signal.

International Classification:

H03G 3/10

US Classification:

330284, 333 81 R, 4552321

Abstract:

An integrated receiver with channel selection and image rejection substantially implemented on a single CMOS integrated circuit is described. A receiver front end provides programable attenuation and a programable gain low noise amplifier. Frequency conversion circuitry advantageously uses LC filters integrated onto the substrate in conjunction with image reject mixers to provide sufficient image frequency rejection. Filter tuning and inductor Q compensation over temperature are performed on chip. The filters utilize multi track spiral inductors. The filters are tuned using local oscillators to tune a substitute filter, and frequency scaling during filter component values to those of the filter being tuned. In conjunction with filtering, frequency planning provides additional image rejection. The advantageous choice of local oscillator signal generation methods on chip is by PLL out of band local oscillation and by direct synthesis for in band local oscillator.

US Classification:

324765

Abstract:

A system or apparatus for monitoring an Integrated Circuit (IC) chip, comprises: a sense circuit at least partially constructed on the IC chip and configured to produce one or more sense signals each indicative of a corresponding process-dependent circuit parameter of the IC chip; and a digitizer module configured to produce, responsive to the one or more sense signals, one or more digitized signals each representative of a corresponding one of the sense signals. A controller is configured to determine a value of one or more of the process-dependent circuit parameters based on one or more of the digitized signals.

US Classification:

324763, 324765, 3241581, 714721, 714733

Abstract:

A method and system for monitoring and compensating the performance of an operational circuit is provided. The system includes one or more integrated circuit chips and a controller. Each integrated circuit chip includes one or more operational circuits, each operational circuit having at least one controllable circuit parameter. Each integrated circuit chip also includes a process monitor module at least partially constructed thereon. The controller is coupled to each process monitor module and to each operational circuit. The controller includes logic for evaluating the performance of an operational circuit based on data obtained from process monitor module and operational circuit related data stored in a memory. Based on the evaluation, the controller determines whether any deviations from desired or optimal performance of the circuit exist. If deviations exist, the controller generates a control signal to initiate adjustments to the operational circuit to compensate for the deviations.

Assignee:

Broadcom Corporation - Irvine CA

International Classification:

H03G 3/00
H03G 3/20

US Classification:

330141, 330278

Abstract:

The present invention provides systems and methods for asymmetrically varying gain in a low noise amplifier. The amplifier includes a first stage amplifier, a plurality of second stage amplifiers coupled to the first stage amplifier, a comparator coupled to one of the second stage amplifiers, and a controller coupled to the comparator, the first stage amplifier, and the plurality of second stage amplifiers. The controller is configured to produce one or more gain control signals to change the gain of one of the first stage amplifier or the plurality of second stage amplifiers at a plurality of asymmetric rates so as to cause the power of the output signal to move toward one of the threshold values of the comparator. The rate of change of the gain is based on conditions including the gain of the first stage amplifier, gain of a second stage amplifier, and the sampled power level.
