Bit-adjacency capacitor-switched DAC, method, driver and display device

摘要

A cyclic digital to analog converter (CDAC) includes: first and second capacitors C 1 and C 2 ; an arrangement of switches selectively controllable to connect C 1 and C 2 in one of at least two charging-and-sharing configurations, the first configuration having the first capacitor C 1 as a charging capacitor CCH and the second capacitor C 2 as a sharing capacitor CSH, namely CCH=C 1 and CSH=C 2 , and the second configuration having CCH=C 2 and CSH=C 1 ; and a controller to toggle the arrangement of switches between the first and second configurations based upon adjacent bits of a given input word.
