  • Device and method for receiving and processing RF signals, a method for providing digital calibration values for such a device and a receiver incorporating the device
    Patent number: 7680472
    Abstract: A device for receiving a RF signal over multiple channels, a receiver incorporating the device, a method of providing digital calibration values for a digitally-tunable resonant circuit of the device, and a method of processing an RF signal. In one embodiment the device includes: (1) a low-noise amplifier having a digitally-tunable resonant circuit, (2) a memory configured to store digital calibration values particular to the device and (3) a time-constant controller coupled to the low-noise amplifier and configured to retrieve from the memory at least one of the digital calibration values as a function of a channel to be received and, based on the at least one, to cause the digitally-tunable resonant circuit to provide a time-constant corresponding to the channel to be received.

  • Speed-up mode implementation for direct conversion receiver
    Patent number: 7062244
    Abstract: A speed-up mode control system is operative to generate a speed-up mode signal based on a gain control signal from associated digital circuitry. The speed-up mode signal controls electronics associated with one or more amplifiers to facilitate settling time of an output signal of the amplifier(s) that occurs when the gain of the amplifier changes. The gain control signal also can be delayed to provide a delayed version of the gain control signal for controlling gain of the amplifier(s).
