Abstract:This paper presents the design and implementation of a fully on-chip wideband low noise amplifier (LNA) using 0.25-micron Silicon-on-Sapphire (SOS) technology for the next-generation Square Kilometre Array (SKA) radio telescope application. Ultra low noise and wideband operation are the principle design challenges in LNA for SKA application. The proposed LNA design employs cascaded inductive degeneration architecture and achieves broadband matching by using on-chip high quality factor (Q) SOS inductors inter-s… Show more
