專利摘要(中)
一種適用於將一（2N-2）級脈波幅度調變格式的類比輸入訊號轉換為一N位元寬的數位輸出訊號的連續近似式類比至數位轉換器，包含一開關電路、一轉換電路、一比較電路、一暫存器及一控制器。該開關電路用於接收共同表示該類比輸入訊號的一第一輸入電壓和一第二輸入電壓。該轉換電路輸出一第一比較電壓和一第二比較電壓。該比較電路比較該第一比較電壓和該第二比較電壓產生一比較輸出。該暫存器根據該比較輸出產生該數位輸出訊號。該控制器根據該比較輸出選擇性地提供一參考電壓或一接地電壓的其中之一至該轉換電路。

專利摘要(英)
A successive approximation ADC includes a switch circuit, a conversion circuit, a comparison circuit and a controller. The conversion circuit outputs first and second comparison voltages that are respectively equal to first and second input voltages when the switch circuit operates in an ON state. The comparison circuit compares the first and second comparison voltages to generate first and second comparison signals. Generation of least significant bits of the first and second comparison signals is related to two first capacitors and two second capacitors of the conversion circuit. When the other bits of the first comparison signal have identical logic values, the controller provides two different voltages respectively to the first capacitors and respectively to the second capacitors; and when otherwise, the controller provides one of the voltages to both of the first capacitors, and provides the other one of the voltages to both of the second capacitors.
