摘要: This paper presents the design of a Ka-band two-stage LNA for System-on-Chip (SoC) space-based radiometers. The circuit features proper self-adaptive compensation to achieve robustness against temperature variations. technology selected is 250nm SiGe BiCMOS from IHP foundry. selection motivated by space qualification above process, which under development at IHP. An automatic procedure inductors has been developed on purpose. Preliminary simulations designed show conversion gain 24 dB 31.4 GHz with noise figure 3.5 dB. obtained sensitivity very promising total power radiometric applications.
