The voltage transfer characteristics (VTC) of a complementary metal-oxide-semiconductor (CMOS) inverter provides necessary information about some of the most important performance parameters, such as noise margin (low/high), inverter logic threshold voltage, and so on. Over years, there has been an...
The core VTC architecture uses a modified current starved inverter biased in subthreshold to maintain low-power consumption level. A prototype of the proposed VTC is implemented in 130nm CMOS technology, it exhibits a nonlinearity of 1 % per 150-mV for single-ended architecture, while exhibits ...
