Since the CMOS technology scaling has focused on improving digital circuit, the design of conventional analog circuits has become more and more difficult. To overcome this challenge, there have been a lot of efforts to replace conventional analog circuits with digital implementations. Among those approaches, this paper gives an overview of the latest achievement on utilizing a CMOS inverter as an analog circuit. Analog designers have found that a simple resistive feedback pulls a CMOS inverter into an optimum biasing for analog operation. Recently developed applications of the resistive-feedback inverter, including CMOS inverter as amplifier, high-speed buffer, and output driver for high-speed link, are introduced and discussed in this paper.
