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