Abstract :
The authors present experimental results of a 2 to 18 GHz high-gain dual-stage feedback amplifier employing a novel concept of current sharing that drastically reduces the current consumption by 50% without compromising the amplifier performance and hence produces a more than two-fold improvement in the power-added efficiency
