Voltage generating circuit and method |
摘要 |
A voltage generating circuit and method thereof for preventing a current from flowing from a voltage generating node to a pumping node in transiting of the circuit from an active operation to a pre-charge operation are provided. The voltage generating circuit comprises a pre-charge circuit for pre-charging a pumping node and a voltage transmitting control node during a pre-charge operation; a voltage pumping circuit for pumping a signal at the pumping node during an active operation; a voltage transmitting circuit for transmitting the signal from the pumping node to a voltage generating node in response to a signal at the voltage transmitting control node during the active operation; and a courtercurrent preventing circuit for varying the signal at the voltage transmitting control node based on the signal at the pumping node during the pre-charge operation and for preventing a current from flowing between the pumping node and the voltage transmitting control node during the active operation.
