A 10-bit Serial Integration-Type DAC Architecture for AMLCD Column Drivers

摘要

A 10-bit serial integration-type DAC architecture based on discrete-time integrator using switched-capacitor structure is proposed for AMLCD column drivers in this paper. This proposed serial DAC architecture can dramatically reduces its size by minimizing the size of capacitors used for integration using a simple capacitor swapping algorithm per frame. The design of the proposed DAC was dedicated to mobile application and has been fabricated in 0.35μm 3.3V CMOS process.
