In this paper, based on small signal models of hetero-junction bipolar transistors (HBTs) with different feedback circuits, the expressions for S parameters of the device are derived to analyze the influence of different feedback technologies on amplifier performance, especially on the stability and the gain flatness of Ultra-Wideband Low Noise(More)
—A low power cascode SiGe BiCMOS low noise amplifier (LNA) with current reuse and zero-pole cancellation is presented for ultra-wideband (UWB) application. The LNA is composed of cascode input stage and common emitter (CE) output stage with dual loop feedbacks. The novel cascode-CE current reuse topology replaces the traditional two stages topology so as to(More)
