  • Abstract
    A dynamic biasing method for enhancing PAE while controlling the bandwidth of the gate and drain bias signals has been presented. Simulation with a modulated signal shows a 40 point increase in PAE with an increment of 3dB in ACPR compared to a class-A amplifier. Such a system would require a drain bandwidth of only 2 times the RF signal bandwidth, which is only a fraction of that used in standard Envelope Tracking.
