Abstract:
1. An apparatus comprising: a mixer block having a first voltage input, the mixer block comprising a plurality of mixer unit cells, each mixer unit cell having a mixer unit voltage input and a mixer unit current input, wherein the first voltage input is coupled to the mixer unit voltage input of each mixer unit cell, a transconductance (Gm) block having a second voltage input, the Gm block comprising a plurality of Gm unit cells sharing common drains, each Gm unit cell coupled to the second voltage input and comprising a plurality of transistors and configured to convert the second voltage input into a Gm unit cell current output, wherein a plurality of Gm unit current outputs are conductively coupled together; and a conductive path coupling the conductively coupled plurality of Gm unit current outputs to the mixer unit current input of each mixer unit cell; wherein the conductive path comprises a single conductive lead configured to carry a sum of the conductively coupled Gm unit current outputs to the mixer unit current inputs of each of the plurality of mixer unit cells.
