[paper] OTA using the Open Sky130 PDK
doi: 10.5281/zenodo.10646550
Faculdade de Engenharia, Universidade Federal de Juiz de Fora, Brazil
Abstract: This paper describes the design, layout and simulation of a linear transconductance Operational Transconductance Amplifier (OTA) using the SkyWater 130nm 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.
(b) Alternative source degeneration triode MOSFETs; and its GDSII layout, with identification of some relevant parts: (A) differential pair; (B) source-degeneration resistors; (C) biasing transistors.
Acknowledgment: This work is result from a scientific initiation project covered by the VI VIC 2022/2023 Program, by PROPP/UFJF.
