Abstract :
Describes the design of 2 GHz LC-oscillator for IMT-2000 frequency band application. The LC-oscillator has a simple automatic swing control circuit for providing constant output power to mixer and prescaler. Total circuit consists of oscillator core, buffer, bandgap reference and drive amp. The oscillator core consumes 1.3 mA. A frequency tuning range is about 360 MHz. The output power of the LC-oscillator varies within 1.1 dBm. This chip is implemented in 60 GHz SiGe BiCMOS process by ST Microelectronics. Total power consumption is 31.5 mW at a 2.7 V single power supply
