发明名称 Precision capacitor ladder using differential equal-perimeter pairs
摘要 <p>An integrated circuit capacitor ladder which uses a differential pair of capacitors for each step in the ladder. By pairing a square with a rectangle of equal perimeter, the contributions of edge and corner elements can be canceled out. This adds area and complexity, but greatly increases the precision of scaling. &lt;IMAGE&gt;</p>
