This rail-to-rail output class-AB single-stage amplifier is designed for display applications. To overcome weaknesses of the single-stage amplifier, a low DC gain and a low slew-rate, the proposed amplifier uses different-ratio current-mirrors (DRCMs) and positive feedback loops (PFBs). In addition, the proposed amplifier can drive wide range of capacitive load (Co) owing to the single-stage structure. The prototype chip was fabricated in a 0.18 μm CMOS technology for a power supply of 1.8V. |
