Abstract :
A 5.8GHz fully integrated common-gate LNA uses a gm-boosting technique and draws 1.9mA from a 1.8V supply with 9.4dB gain 7.6dBm IIP3, and 2.5dB NF. A Colpitts differential VCO (QVCO) employs a similar method and draws 3.6mA (4.3mA) from a 2V supply. Phase noise at 50kHz and 1 MHz offset frequencies are -97dBc/Hz (-104Bc/Hz) and -128 dBc/Hz (-127dBc/Hz), respectively.
