A method and apparatus are provided for providing improved radio frequency
(RF) receiver signal correction. For RF receiver circuitry (106) having
receive path and a warmup period associated therewith and including at
least one analog baseband gain control stage (218) having a gain
associated therewith, the method includes the step of performing a DC
correction calculation operation during the warmup period to derive a DC
correction value having a first component and a second component for each
of the at least one gain control stage (218). The DC correction
calculation step includes the steps of performing a first closed loop
correction (460) of a baseband path to derive the first component of the
DC correction value and performing a second closed loop correction (462)
of the receive path as a function of the (218) gain during the warmup
period to derive the second component of the DC correction value. During
operation after the warmup period (464, 466), an open loop correction is
performed for instantaneous DC correction as function of the PMA (218)
gain and the DC correction value.
