DACs in data-driver ICs for Active-Matrix LCD (AMLCD) systems play the key role of data voltage generation. Especially stringent requirements are imposed on the DACs for AMLCD data drivers: uniform performance in each data channel, and compactness in chip implementation, as well as extremely low power consumption. The prevalent use of resistor-DAC (RDAC)(More)
