Development of a Baseband Amplifier for a 130 nm CMOS process using open-source design flow

This paper addresses an analog-type integrated circuit development using open-source tools and process design kit. The SkyWater 130 nanometer CMOS process was used to design an operational transconductance amplifier current-mirror as a core of an AC-coupled Amplifier. So, AC-coupled amplifier applications were discussed, as well as an overview of the analog integrated circuit design flow and the open-source EDA tools used in each step. Simulations and results are presented and compared with other works in the state of the art. The performance of open-source tools and open-source process design kit are properly assessed.
