Fifty Applications of the CMOS Inverter—Part 3 [The Analog Mind]

In this multipart article, we study applications of the CMOS inverter in today’s electronic systems. We quantify the performance of each circuit by simulations in the slow–slow corner of 28-nm technology with VDD = 0.95 V at T = 75 °C. The reader is cautioned that inverters suffer from poor supply rejection, requiring on-chip voltage regulators.
