Patent number: 8315587Abstract: In one implementation, a receiver may have an analog front end with an amplifier to receive a radio frequency (RF) signal and a mixer to downconvert the signal to a baseband signal. Then, a demodulator may receive the baseband signal and obtain an audio signal therefrom. Still further, a controller may be coupled to receive a control signal corresponding to a variable impedance level, and control a local oscillator coupled to the mixer responsive to the control signal. The variable impedance may be controlled by a user to tune to the channel.Type: GrantFiled: August 29, 2008Date of Patent: November 20, 2012Assignee: Silicon Laboratories Inc.Inventors: Shahram Tadayon, Wade Robert Gillham, Peter J.

Patent number: 8126420Abstract: In one embodiment, the present invention includes a method for digitizing a phase noise value indicative of a level of phase noise present in a LO signal and downconverting an RF signal to a second frequency signal using the LO signal. This downconversion can cause the phase noise to be transferred to the second frequency signal. The method may thus further include removing the phase noise from the second frequency signal using the digitized phase noise value.Type: GrantFiled: December 27, 2007Date of Patent: February 28, 2012Assignee: Silicon Laboratories Inc.Inventors: Mustafa H.
