Patent number: 9020425Abstract: A NFC communications enabled device has a data store to store data, an inductive coupler to couple inductively with the magnetic field of a radio frequency signal and a signal supplier to supply a radio frequency signal to the inductive coupler. A modulator modulates a radio frequency signal in accordance with data and a demodulator extracts data from a modulated radio frequency signal inductively coupled to the coupler. A controller enables the NFC communications enabled device both to initiate near field radio frequency communication with another near field RF communicator and to respond to near field radio frequency communication initiated by another near field RF communicator. The inductive coupler has an antenna and a variable impedance element. The controller is configured to control the variable impedance element to control a magnetic field strength associated with a radio frequency signal supplied by the signal supplier.Type: GrantFiled: July 25, 2012Date of Patent: April 28, 2015Assignee: Broadcom Europe LimitedInventor: Peter Symons

Patent number: 9020067Abstract: Distortion and aliasing reduction for digital to analog conversion. Synthesis of one or more distortion terms made based on a digital signal (e.g., one or more digital codewords) is performed in accordance with digital to analog conversion. The one or more distortion terms may correspond to aliased higher-order harmonics, distortion, nonlinearities, clipping, etc. Such distortion terms may be known a priori, such as based upon particular characteristics of a given device, operational history, etc. Alternatively, such distortion terms may be determined based upon operation of a device and/or based upon an analog signal generated from the analog to conversion process.
