A new low-noise amplifier topology to rival conventional designs

摘要

A novel current-mode BiCMOS low-noise amplifier is compared to conventional voltage-mode topologies, emphasising on performance at 900 MHz. Rivalling classical designs in performance, this new design has the added advantage of controllable gain. Comparisons in terms of the major parameters: gain, noise figure, power consumption, signal quality: reveal that this new approach provides excellent possibilities.
