摘要： An integrated circuit radio transceiver and method therefor comprises circuitry that is operable to up-convert an outgoing continuous waveform signal to RF and that is further operable to down-convert and ingoing RF signal to one of a baseband or intermediate frequency in a manner that provides a linearized output current having an amplified current magnitude for mixing with a local oscillation in a mixer block. Specifically, a circuit portion is operable to produce a linearized current based upon an input signal. The linearized current is then produced to a current mirror block that produces a scaled and amplified output current. The scaled and amplified output current is then produced to a mixer block for mixing with a local oscillation to create the outgoing RF signal or the ingoing baseband or intermediate frequency signal.

摘要： The present invention provides adjusting of a radio frequency (RF) receiver that includes processing that begins by enabling an initial setting of the RF receiver, wherein the initial setting is based on a bandwidth of a channel of a plurality of channels. The processing continues by receiving an RF signal containing a preamble of a frame via one of the plurality of channels. The processing continues by converting the RF signal to a baseband signal based on the initial setting. The processing continues by determining channel type of the one of the plurality of channels based on the baseband signal. The processing continues by determining whether the channel type corresponds to the bandwidth of the initial setting. The processing continues by, when the channel type does not correspond to the bandwidth of the initial setting, adjusting setting of the RF receiver based on the channel type.

摘要： In one embodiment of the present invention, two crystal oscillator circuits are coupled in parallel to provide differing performance according to mode. Generally, a first circuit provides low phase noise and high accuracy while a second circuit provides greater phase noise within an acceptable tolerance while consuming significantly less power in a low power mode of operation. The second circuit includes an entirely separate amplifier for the low power operation that tolerates a relatively smaller input signal swing but that consumes even less power. The first circuit, which comprises selectable amplification elements, and the second circuit are coupled in parallel with selectable resistive elements and capacitive elements to provide varying amounts of amplification and filtering according to whether an operational mode is in a startup mode, a normal mode, or a low power mode of operation.
