Half-ratio charge pump circuit

A half-ratio charge pump circuit includes a flying capacitor electrically coupled between a first node and a second node. Eight switches are controlled to carry out first to fourth operating phases during which charges are stored on and transferred from the flying capacitor, thereby generating a pos...

Zusammenfassung:A half-ratio charge pump circuit includes a flying capacitor electrically coupled between a first node and a second node. Eight switches are controlled to carry out first to fourth operating phases during which charges are stored on and transferred from the flying capacitor, thereby generating a positive output voltage at approximately half the positive input voltage, and generating a negative output voltage at approximately half the negative input voltage.
