Analog design challenges in nanometer CMOS technologies

This paper provides a review of all important effects in nm CMOS technologies, with 1 volt supply voltages. They are the reduction of the transconduction, the increase of the gate current, the noise and the mismatch. It is followed by an overview of amplifiers/filters configurations with both Gate and Bulk drives. A large number of sub-1 volt circuits are then provided for sake of illustration, including sigma-delta modulators.
