Claim Text:
1. An apparatus comprising: a trans-conductor coupled to a first mixer to output a first signal to a trans-impedance amplifier (TIA), the TIA comprising a first trans-conductor having a first trans-conductance gain and a second trans-conductor having a second trans-conductance gain, an input to the first trans-conductor coupled to the output of the first mixer, an input to the second trans-conductor coupled to the output of an R-C network, the output of the first trans-conductor directly connected to the output of the second trans-conductor; the R-C network having an input coupled to the output of a passive mixer, and to output a second signal to the TIA to generate an output voltage; and a buffer stage having an input coupled to the first and second trans-conductor outputs.
