On Optimizing Capacitor Array Design for Advanced Node SAR ADC

Analog Integrated Circuit Routing Techniques: An Extensive Review

“…While this greatly reduced the complexity of the problem, the number of candidate routes selected for each wire is still a delicate tradeoff to be decided a priori. Recently, Chiang et al (2022-2023) [175][176] used an ILP routing technique to automate finger-capacitor array synthesis for custom successive-approximation register ADCs, where the problem was severely constrained in order to reduce the generation time.…”
