技術簡介
循續漸近式類比數位轉換器(Successive Approximation Register ADC, SAR ADC)具有面積小、及低功耗等特點,適合低功耗及SOC等應用,如: 穿戴式裝置、手持式裝置、及感測器等。該晶片採用非同步架構設計可提高取樣速度,且無需使用鎖相迴路(Phase Lock Loop, PLL)電路,便於系統晶片整合(System on Chip, SoC)。
Abstract
Successive Approximation Register (SAR) ADC has small area and low power consumption, which is especially suitable for wearable, handheld, and sensor applications. Besides, The SAR ADC adopts asynchronous architecture to improve sampling rate and no need of PLL, easy to integrate with SOC.
