Abstract

A radio frequency receiver (30, 32), includes a first component block (12, 16, 18, 20); a second compensating component block (22, 22a-22b, 34); and control circuitry (26) operable for controlling the state (e.g., load, bias, gain) of the first component block. When the control circuitry (26) causes a change in the state of the first component block that is expected to induce a DC offset in a signal, the control circuitry (26) changes the state of the second component block to compensate for an estimate of the DC offset. Preferably, the second component block is a filter (22, 22a-22b, 34), that temporarily changes from a nominal cutoff frequency to an elevated cutoff frequency so that voltage will settle quickly and accurately at an estimated voltage, the estimated voltage being predetermined and based on the state change to the first component block. A method is also described for practicing the invention.
