This paper describes ongoing work toward a FinFET-friendly implementation of high-speed DA converters for mm-wave arrays. The proposed architecture is based on massively-parallel charge redistribution, and separates level generation, pulse timing and output power generation. This approach aims to maximally leverage the advantages of FinFet technology transistor speed and density and simultaneously mitigate its main shortcomings poor interconnect delay and current handling. As a proof of concept, we will design 6-8 bit prototypes operating at up to 120 GSsin 16 nm FinFET CMOS.
