  • Patent number: 9800135
    Abstract: A ripple suppressor suppresses ripples of a channel current. The ripple suppressor comprises a voltage-controlled current source, a stabilizer, and an auto-calibration circuit. A control voltage at a control node controls the channel current flowing through a path connecting first and second channel nodes. The voltage-controlled current source receives a current-setting signal to generate the control voltage, so as to stabilize the channel current in response to the current-setting signal. The stabilizer at least provides low-pass filtering to generate and stabilize the current-setting signal in response to a first channel voltage at the first channel node. The auto-calibration circuit controls the stabilizer in response to the control voltage, so as to make the control voltage in compliance with a first predetermined condition.
