  1. Low-noise amplifier in 0.12μm standard CMOS technology for K-band ELECTRONICS LETTERS 12th May 2005 Vol. 41 No. 1 Chien-San Wu

  2. Outline • Introduction • Amplifier design • Measurement results • Conclusions • References

  3. Introduction • For RF circuits operating above 20 GHz, CMOS offers cost-effective and single-chip solutions with potential for radar and high-bandwidth wireless commun- ication applications. • The amplifier achieves a gain of 18.86 dB and a noise figure of 4.26 dB at 20.3 GHz.

  4. Amplifier design The circuit employs three cascaded cascode stages to obtain sufficient gain and stability at the design frequency. To further improve the stability, microstrip transmission lines (TRL) have been used for the source degeneration. A high quality factor of the inductors is essential to obtain the targeted input impedance at high frequencies.

  5. Amplifier design The current consumption is 38 mA from a 1.5 V voltage supply.
