Abstract :
For the LCDs used in the mobile terminals, low power dissipation and high speed operation are required. In this paper, high speed, low power dissipation and rail-to-rail input/output class AB amplifier is proposed. In the proposed circuit, the number of current paths was reduced and the phase compensation suitable for high speed operation was employed. The proposed circuit was fabricated using 0.13 mum process. The supply voltage is 5 V and the current dissipation is 2 muA. The settling time within 2 musec at both rising and falling edges was achieved.
