METHOD AND CIRCUIT FOR CHARGING AND DISCHARGING A CIRCUIT NODE |
摘要 |
<p>A voltage circuit and method charges a circuit node to a first predetermined voltage. The first predetermined voltage charged onto the circuit node is used for a first predetermined function during a first time period. A portion of charge from the circuit node is removed to circuitry coupled to the circuit node. The portion of the charge is reused during a second time period subsequent to the first time period. In one form a voltage generator has diode configurable transistors for passing current in only one direction depending upon whether the circuit node is being charged or discharged. In another form a switch couples the circuit node between a reference terminal and another circuit for charge reuse. Reuse of charge permits increased power savings.</p> |
