1. An amplifier, comprising:
a plurality of transistors, wherein a respective gate terminal of each of two transistors of the plurality of transistors are tied together via a common connection; and
a local common mode feedback resistor coupled between the common connection and respective terminals of the two transistors, wherein the local common mode feedback resistor comprises:
a first plurality of resistors coupled in series between the common connection and the respective terminal of a first of the two transistors; and
a first metal oxide semiconductor (MOS) resistor coupled in parallel with one or more of the first plurality of resistors, wherein the first MOS resistor provides different levels of resistance to different process corners.
