Abstract :
A 5 GHz, 56 dB voltage gain Low Noise Amplifier with built-in tunable center frequency and 30 MHz bandwidth channel selection filter was implemented using 0.18 μm CMOS process. Using compact high quality-factor 3-dimensional solenoid on-chip inductors, the LNA drains 0.9 mA current from the 1.5 V power supply and has 6.5 dB noise figure. The power consumption can be further reduced if a smaller gain is desirable.
