Active Body-Bias Linearization for Wide-Band GmC Based Continous-Time Sigma-Delta ADCs in 22 nm FD-SOI

We present a linearization technique for differential transconductors in fully depleted silicon-on-insulator (FD-SOI) CMOS technology. Here, dynamic self-biasing is employed at the back-gate node, thereby the non-linearity of the main differential input pair is compensated.
