Abstract:
|
This paper addresses the design of high-Q passive
inductors and differential transformers in a low-power lownoise
amplifier (LNA) application. The passives quality in
resonant LC tanks as well as in the matching network and
degeneration inductors has been improved by balancing the
trade-off between ohmic losses and Eddy current degradation.
As a result, the enhanced passives Q-factor for the optimized
passive devices has been used in order to design a 2.4 GHz fully
integrated high-gain current-reused LNA, implemented in 0.18
μm CMOS technology. The LNA performance show a gain of
roughly 30 dB, while dissipating 0.9 mA from a 1.2 V supply. |
