Method and Apparatus for Charge Leakage Compensation for Charge Pump with Leaky Capacitive Load |
摘要 |
An apparatus comprises a charge pump to receive a phase signal representing a result of a phase detection and to output a current flowing between an internal node of the charge pump and an output node of the charge pump; a capacitive load coupled to the output node; a current source controlled by a bias voltage to output a compensation current to the output node; a current sensor coupled between the internal node and the output node to sense the current; and a feedback network to generate the bias voltage in accordance with an output of the current sensor. A comparable method is also disclosed.
