Abstract:

The design of two 2.4 GHz CMOS LC balanced oscillators in a 0.25 /spl mu/m process for Bluetooth specifications is presented. These oscillators achieve low phase noise with low power consumption. At a frequency offset of 3 MHz from the 2.4 GHz carrier, the simulated phase noise is -132 dBc/Hz for both oscillators with a power dissipation of 5-11 mW from a 2.5 V power supply. A wide tuning range of 18% is obtained by means of a PMOS varactor in conjunction with an array of switched capacitors.
