Abstract :
The paper presents the design of a wideband low noise amplifier (LNA) with self-healing technology that can simultaneously adjust both the peak gain frequency and the input matching frequency to the operating frequency. The gain of proposed LNA is also adjustable. The proposed self-healing LNA is implemented in a 0.13um SiGe BiCMOS technology. The operating frequency of the proposed LNA can be adjusted from 4.5GHz to 7.8GHz. The LNA achieves typical gain of 19dB with 14dB continuous tuning range. The measured input matching is below -12dB over the entire frequency band. The measured noise figure of the LNA is 4.2dB at 7.8GHz, and the output 1dB compression point is -9dBm. The LNA dissipates 52mW power.
