Abstract

Abstract:
In this paper, a new method for the design of the broadband RF/microwave amplifiers
employing distributed amplification is presented. It proposes to use stages with asymmetric
lumped elements (inductances and capacitances) in the gate and drain circuits of the
amplifier instead of symmetric elements in order to control the frequency response and to
achieve a flat gain over a large bandwidth. The need for impedance matching problems is
also solved. Simulation result obtained demonstrates that the new design gives better
frequency response as compared to the conventional distributed amplifiers even without
optimization.
