摘要：
The charge pump comprises a negative current source (406) operative to selectively discharge a loop filter (202) with substantially constant negative current that is substantially linearly dependent on a first reference voltage and a positive current source (404) operative to selectively charge the loop filter with substantially constant positive current that is substantially linearly dependent on a second reference voltage
