Abstract
In this paper a detailed investigation of LNA noise using negative transformer feedback matching is performed. It is shown, that the transformer matching technique (TMT) is well suited for full on-chip integration of the necessary inductors and it also enables a low noise figure while conjugate complex matching is performed. To prove the assumption analytical calculations using a simplified VBIC-transistor model for noise behavior and for the calculation of the input impedance are performed and verified with simulations of transistors in IHP 130 nm-SiGe-BiCMOS. The models used are verified by measurements of a fabricated LNA.
