    摘要: A charge-pump includes a first charge-pump sub-circuit having a control terminal that communicates with a first bias voltage line. A first charge-pump mirror sub-circuit regulates current on the control terminal. A first capacitance and a first ripple reducing sub-circuit communicate with the first bias voltage line. A second charge-pump sub-circuit and a second charge-pump mirror sub-circuit communicate with a second bias voltage line. A second capacitance and a second ripple reducing sub-circuit communicate with the second bias voltage line. An output communicates with the first and second charge-pump sub-circuits.
