The design of two 2.4GHz CMOS LC balanced oscillators in the 0.25μm
National BiCMOS process for Bluetooth specifications is presented. These oscillators
achieve low phase noise with low power consumption. At a frequency offset of
500KHz from the 2.11GHz carrier, the measured phase noise is -101.9dBc/Hz for the
NMOS oscillator with a power dissipation of 12.5mW. The complementary oscillator
has a phase noise of -103.6dBc/Hz at 500KHz offset from the 2.19GHz carrier and a
power dissipation of 6.25mW from a 2.5V power supply. A wide tuning range of 16%
is obtained by means of a PMOS varactor in conjunction with an array of switched
capacitors. / Graduation date: 2002
