Abstract
Feeding the common-source amplifier output to the back-gate terminal in fully depleted silicon on insulator (FD-SOI) technology exploits the linearizing effect of negative feedback. Analysis and simulation results in 22 nm FD-SOI show that back-gate feedback sets the overall gain approximately independent of the load, contributes no additional noise, and improves linearity by the back-gate voltage gain. Third-order intercept point (IP3) enhancement is at least compared to without feedback in inverter-based, or complementary common-source, differential amplifiers.
