Consider variable threshold CMOS fabricated in 0.25-mm technology with tox = 7 nm. The n-MOSFETs and the p-MOSFETs have 2 x 10^16 cm^-3 channel doping; ±3.3 V is available for active body biasing of the MOSFETs. The standby threshold voltages (with body bias) are to be ± 0.3 V. What is the minimum value for the absolute value of the nominal threshold voltages (as fabricated, without body bias)?
