Design of LNA using on-chip inductor for Ku-band application

A simple LNA design scheme operating at Ku-Band (17 GHz) is presented in this paper. The concept has been validated in 0.09 pm CMOS process using on-chip inductors. It has been shown that the on-chip inductor technique reduces the contribution of spectral noise current due to inductor series resistance and also provides a good matching at the LNA input and output at Ku-Band. The on-chip inductor also allows fine control and adjustment of resonance frequency.
