58.1: A 720-Channel LCD Source Driver with a 12-Bit Segmented R-C DAC

A 720‐channel LCD source driver with a 12‐bit segmented R‐C DAC has been designed and fabricated by a 16V CMOS process. The proposed DAC consists of a conventional resistor string and a sample‐and‐hold buffer. DNL less than 0.3LSB and output voltage deviations less than 3mV were measured. Die area i...

Zusammenfassung:A 720‐channel LCD source driver with a 12‐bit segmented R‐C DAC has been designed and fabricated by a 16V CMOS process. The proposed DAC consists of a conventional resistor string and a sample‐and‐hold buffer. DNL less than 0.3LSB and output voltage deviations less than 3mV were measured. Die area is 24.9mm2.
