Abstract:
1. A switch capacitor circuit comprising: a voltage source having a first terminal and a second terminal; a first capacitor; a second capacitor; a third capacitor; a fourth capacitor; a first pair of switches configured to couple the first capacitor in parallel to the second capacitor, wherein one switch of the first pair of switches is configured to couple the second capacitor to the first terminal of the voltage source; a second pair of switches configured to couple the third capacitor in parallel to the fourth capacitor, wherein one switch of the second pair of switches is configured to couple the third capacitor to the second terminal of the voltage source; a third pair of switches configured to couple the first capacitor in parallel to the third capacitor, wherein one switch of the third pair of switches is configured to couple the third capacitor to the first terminal of the voltage source; and a fourth pair of switches configured to couple the second capacitor in parallel to the fourth capacitor, wherein one switch of the fourth pair of switches is configured to couple the second capacitor to the second terminal of the voltage source.
