 技術摘要 / Our Technology： |
一種連續近似式類比至數位轉換器,包含一個開關模組、一個轉換模組、一個比較器及一個控制模組。開關模組包括兩個分別對應第一及第二輸入電壓的開關單元。每一開關單元包括第一至第三開關,第一與第二開關串聯,第一開關接收相對應的輸入電壓,第二開關電連接轉換模組,第三開關電連接第一與第二開關之間的一個共同節點,接收一個參考電壓,當第一及第二開關導通、第三開關不導通時,允許相對應的輸入電壓被傳遞到轉換模組,當第一及第二開關不導通、第三開關導通時,允許參考電壓被傳遞到第一與第二開關之間的共同節點。
A successive approximation analog-to-digital converter includes: a comparator for comparing first and second comparison voltages from a conversion module and respectively identical to first and second input voltages, which are transmitted to the conversion module via a switch module in an ON state; and a control module for controlling the switch module and the conversion module and generating a digital output that corresponds to a difference between the first and second input voltages based on first and second comparison signals from the comparator and a clock signal. The switch module includes two switch units each having a series connection of first and second switches, and a third switch coupled to a common node between the first and second switches.
