Abstract :
Push-pull buffer amplifiers are operated in a transient mode for column drivers suitable for vertical N-dot inversion of an active-matrix LCD (AMLCD) image. Each channel has a static current draw of 3.8 muA and an area of 4773 mum2. The functionality of the column driver with 720 outputs is fully evaluated on the AMLCD module. The chip size of 23.2mm2 is achieved in a 0.35 mum 13.5V CMOS process.
