<p>An active mixer circuit, and an associated method, includes a feedback element (26) which increases the linearity of the mixer circuit so that the mixer circuit is operable over a wider dynamic range than typically permitted of conventional, active mixer circuits. The mixer circuit includes a transconductance stage (18) including a pair of transconductance transistors (44, 46). Signals are applied through both of the transconductance transistors (44, 46) in parallel. The feedback element (18) is coupled to an output side of a first of the transconductance transistors (44). And, a mixing stage (38) is coupled to an output side of a second of the transconductance transistors (46).</p> |
