Abstract :
In this paper we explore symmetric floating-gate CMOS circuits aimed for ultra-low analog design. The analog transconductance amplifier presented may operate down to 250mV in a STM 90nm CMOS process with an inherent threshold voltage of 270mV. The ultra-low transconductance amplifier has a current boost function and resembles switch-cap and auto-zero circuits. The current boost technique have been used to implement ultra-low voltage digital logic. Simulated data for a ST 90nm CMOS process, using the the Cadence design tool, are included.
