0.4-V Bulk-Driven Operational Amplifier with Improved Input Stage

A new solution for an ultra-low-voltage, low-power, bulk-driven operational amplifier is presented in the paper. The amplifier is based on a new input stage, exploiting the concept of partial positive feedback. As compared with prior work, the proposed input stage offers improvement of all basic per...
