20090245440 | OUTPUT CIRCUITRY FOR MINIMIZING SPURIOUS FREQUENCY CONTENT - A system including first voltage supply circuitry configured to provide a first voltage supply with spurious frequency content and second voltage supply circuitry configured to provide a second voltage supply without the spurious frequency content is provided. The system includes signal generation circuitry configured to generate a first digital signal using a clock signal and the first voltage supply and configured to cause the spurious frequency content on the first voltage supply and output circuitry configured to generate a second digital signal from the first digital signal synchronous with the clock signal using the second voltage supply. | 10-01-2009 |
20110159828 | Configurable Radio Front End - In one embodiment, the present invention includes a single chip radio tuner, which may be adapted within an integrated circuit (IC). The tuner may be provided with a configurable front end to receive and process a radio frequency (RF) signal via a signal path. This configurable front end may be differently controlled depending on a particular radio implementation in which the tuner is adapted. | 06-30-2011 |
20110159829 | Integrating Components In A Radio Tuner Integrated Circuit (IC) For A Tracking Filter - In one embodiment, the present invention includes a method for configuring a single chip radio tuner having a configurable front end, which may be adapted within an integrated circuit (IC). The method may include setting a controller of the tuner with configuration information for a radio in which the tuner is located. Then, control signals responsive to the configuration information can be sent to the configurable front end to configure the tuner. | 06-30-2011 |
20120244825 | Statistical Gain Control In A Receiver - A radio frequency (RF) signal is received in a receiver, and various counts based on information from the signal can be obtained. Counts of a number of samples of the RF signal exceeding first and second thresholds can be accumulated during an accumulation window. From the first of these counts, it can be determined if the count exceeds a first metric corresponding to a first predetermined count value, and if so, a gain of an RF gain element can be reduced. From the second of these counts it can be determined if this count exceeds a second metric corresponding to a second predetermined count value, and if not, the gain can be increased. | 09-27-2012 |
20120249270 | Providing Multiple Inductors For A Radio Tuner - A method includes receiving a desired channel indication in a radio tuner, determining a band of operation in which the channel is located, and if the channel is within a first band coupling multiple inductors into a resonant tank, and if the desired channel is within a second band coupling a single inductor into the resonant tank. | 10-04-2012 |
20130244600 | Integrating Components In A Radio Tuner Integrated Circuit (IC) For A Tracking Filter - In one embodiment, the present invention includes a method for configuring a single chip radio tuner having a configurable front end, which may be adapted within an integrated circuit (IC). The method may include setting a controller of the tuner with configuration information for a radio in which the tuner is located. Then, control signals responsive to the configuration information can be sent to the configurable front end to configure the tuner. | 09-19-2013 |
20140062527 | ISOLATION RECEIVER - An isolation receiver includes at least one isolation capacitor to provide a first logic signal in response to a second logic signal that is provided by a transmitter. The receiver includes a signal processing circuit to amplify the first logic signal to generate an amplified signal, and the signal processing circuit includes a an amplifier to apply a nonlinear function. A comparator of the receiver provides a third logic signal in response to the amplified signal. | 03-06-2014 |
