Patent number: 8848110Abstract: A receiver circuit includes an analog front-end and a digital processing unit. The analog front-end includes an input for receiving a radio frequency (RF) signal, a first control input for receiving a gain adjustment signal, a second control input for receiving a timing signal, and a signal output for providing a digital intermediate frequency (IF) signal. The analog front-end updates gains of a plurality of gain stages according to the gain adjustment signal and in synchronism with the timing signal. The digital processing unit is configured to produce at least one output signal derived from the digital IF signal. The digital processing unit includes a timing recovery circuit configured to generate the timing signal based on the digital IF signal to control timing of the updating gains of each of the plurality of adjustable gain stages.Type: GrantFiled: May 28, 2010Date of Patent: September 30, 2014Assignee: Silicon Laboratories Inc.Inventors: Ramin Khoini-Poorfard, Alan F.

Patent number: 8781421Abstract: Systems and methods are disclosed for time-domain diversity combining of radio frequency (RF) broadcast signals. Two channelized quadrature (I/Q) signals are generated by different tuner circuitry coupled to two different antennas, are converted to frequency-domain signals, and are used to generate frequency-domain diversity weighting signals. The frequency-domain diversity weighting signals are then converted to time-domain weights and applied to the channelized I/Q signals. The weighted and channelized I/Q signals are then combined in the time-domain to provide a time-domain diversity combined signal. The resulting combined signal can be further processed, as desired, such as by using a demodulator to generate demodulated output signals. Disclosed methods and systems can be applied to a variety of receiver systems configured to receive RF broadcast signals.Type: GrantFiled: September 28, 2012Date of Patent: July 15, 2014Assignee: Silicon Laboratories Inc.Inventors: Javier Elenes, Emmanuel Gautier, David Le Goff, Dana Taipale
