Abstract :
In this paper, the design and analysis of a novel non-uniform fully differential distributed amplifier is presented. The gain-bandwidth product of the proposed amplifier designed in a 0.18 μm standard CMOS process reaches a record level of 34.76 GHz. Proved by both the analytical models and the HSPICE simulations, down-sizing the device and inductor sizes of each stage with respect to the preceding stage in a distributed amplifier results in a better gain-bandwidth product. A comprehensive analytical study is carried out to predict the behavior of the amplifier. HSPICE simulations verify the superior performance of the proposed non-uniform distributed amplifier compared to its conventional counterpart in terms of a better gain-bandwidth product and a flat frequency response.
