摘要:
An adaptive capacitor charge/discharge network tailors the rate-of-change of a capacitor. The network includes two circuit groups with two or more parallel circuit branches, each branch including a current source and a controllable switch connected in series. The parallel circuit branches of one group are connected to Vss, and the parallel circuit branches of the other group are connected to Vdd. All the parallel circuit branches are connected to one plate of a capacitor, the other plate of the capacitor is connected to either Vss or Vdd. A control circuit controls the switch status, and incrementally controls the charge/discharge of the capacitor according to a predetermined order and a predetermined timing sequence to achieve a desired tailored charge/discharge curve.
