Voltage generation circuits and methods of operating same that use charge sharing to increase voltage step-up |
摘要 |
A voltage generation circuit generates an output voltage at an output node thereof by sharing charge between a first node and a second node so as to increase a potential at the second node from a first voltage to a second voltage. The first node is charged to a third voltage and the second node is driven to a fourth voltage that is greater than the third voltage. Charge is shared between the first node and the second node so that the first and second nodes reach a common fifth voltage, which is between the third and fourth voltages. The first node is driven to a sixth voltage, which is greater than the fourth voltage. Charge is shared between the first node and the output node to generate the output voltage thereat.
