摘要

本文首次探讨了用于IEEE 802.3an 10Gbase-T收发器的开源高性能放大器的可行性。该设计基于130nm的Skywater PDK,仅使用免费的开源工具进行开发。布局后仿真表明,该放大器兼容10Gbase-T规范,在典型角点处总谐波失真(THD)为- 51.9dB,信噪比(SNR)为60dB。最后,这里采用的开源设计目标使HPA可复制、可修改,并可直接用作集成电路设计项目中的子电路。

High Performance Amplifier in 130nm CMOS Technology using an Open Source Design Flow for 10Gbase-T Ethernet Transceivers
This article explores for the first time the feasibility of an open source high performance amplifier for IEEE 802.3an 10Gbase-T transceivers. The design is based on the 130nm Skywater PDK and was developed using only free open source tools. Post-layout simulations show that the amplifier is compatible with the 10Gbase-T specification, reaching a total harmonic distortion (THD) of −51.9dB and a signal to noise ratio (SNR) of 60dB in typical corner. Finally, the open source design aim used here makes the HPA reproducible, modifiable and be directly usable as a sub-circuit in integrated circuit design projects.
