CHARGE RECYCLING DRIVER OUTPUT STAGE |
摘要 |
This disclosure provides systems, methods and apparatus for recycling charge. In one aspect, a circuit may include amplifiers with power supplies provided by a capacitor voltage divider. A storage capacitor may be configured to be coupled one at a time and in parallel with individual capacitors of the voltage divider. The storage capacitor may store charge that may be reused. |

1. A circuit for driving an electrode of a display unit, the circuit comprising:
a first amplifier, an output of the first amplifier being coupled with a first terminal of a first switch, the output of the first amplifier capable of providing a voltage in a first voltage range, the first amplifier having a high power supply input associated with a first voltage source and a low power supply input associated with a second voltage source; and a second amplifier, an output of the second amplifier being coupled with a first terminal of a second switch, the output of the second amplifier capable of providing a voltage in a second voltage range different from the first voltage range, a second terminal of the first switch being coupled with a second terminal of the second switch, the second amplifier having a high power supply input associated with the second voltage source and a low power supply input associated with a third voltage source. |
