Abstract: This paper describes the design, layout and simulation of a linear transconductance Operational Transconductance Amplifier (OTA) using the SkyWater 130 nm open Process Design Kit (PDK). By using a known source degeneration technique, it is possible to either decrease and linearize the transconductance of the OTA for a wider range of input voltages, making it proper for use on Gm-C filters. Only open source tools, suited for the Sky130 PDK, were used in this design, showing the applicability to analog designs
