Abstract
A semiconductor integrated circuit to provide a low distortion, large swing intermediate frequency wherein the circuit includes the function of mixing, filtering, and amplification on a single chip. A pair of differential currents are obtained from the mixer, the differential currents are filtered and conditioned, converted to a pair of differential voltages and amplified to obtain the low distortion, large swing intermediate frequency.
