Patent ID: 7884653

Claim:
A source driver with charge sharing, comprising: a first operational amplifier, an output end of the first operational amplifier coupled to a negative input end of the first operational amplifier; a second operational amplifier, an output end of the second operational amplifier coupled to a negative input end of the second operational amplifier; a first switch, a first end of the first switch coupled to the output end of the first operational amplifier; a first resistor, a first end of the first resistor coupled to a second end of the first switch, and a second end of the first resistor coupled to a first data line; a second switch, a first end of the second switch coupled to the output end of the second operational amplifier; a second resistor, a first end of the second resistor coupled to a second end of the second switch, and a second end of the second resistor coupled to a second data line; a third switch coupled in parallel to the first switch; a third resistor coupled in parallel to the first resistor; a fourth switch coupled in parallel to the second switch; a fourth resistor coupled in parallel to the second resistor; and a fifth switch, a first end of the fifth switch coupled to the first end of the first resistor, and a second end of the fifth switch coupled to the first end of the second resistor.
