Abstract :
In this paper we propose a novel design of an ultra low-voltage amplifier using FGUVMOS transistors. Both formal and simulated results confirm a tanh transfer function, using capacitive division for dynamic range scaling, giving rail-to-rail operation. The post-fabrication tuning enables the performance to be matched to the selected power supply. Measured results are presented
