Analog circuits have long relied on the differential-pair as a key amplifier building block used in everything from high precision Opamps to high-speed wireline circuits. With a push to integrating analog circuits in digital-optimized technologies, the early 2000s saw a resurgence of interest in inverter-based circuits, particularly in wireline applications. Examples include source-series terminated line drivers, inverter-based transimpedance amplifiers, optical receiver main amplifiers as well as continuous-time linear equalizers.  

This talk presents an overview of early work in inverter-based amplifiers from the 1960s and 70s that was revived in the late 80s/early 90s for continuous-time filters. A variety of work, mainly for wireline applications will be surveyed, demonstrating the breadth of analog circuit application of the humble CMOS inverter.
