  4. Abstract:
  5. A novel class AB architecture for single stage multipath differential amplifier is presented. The proposed amplifier combines the flipped voltage follower(FVF) for differential input and the nonlinear current mirror for active load. Applying these techniques to telescopic-cascode amplifier increases the unity-gain bandwidth, the DC gain and the slew rate while the same power consumption as the conventional telescopic cascade is achieved
