We present an integrated 60-GHz voltage-controlled oscillator (VCO) and frequency divider (FD) chain in a 0.25-μm SiGe BiCMOS technology. To achieve the wide tuning range, the VCO employs a differential Colpitts configuration and the FD is a regenerative type based on Gilbert-cell mixer and bandpass filter. The VCO-FD chain achieves the tuning range from 54 to 63 GHz and the phase noise of -96.5 dBc/Hz at 1-MHz offset. The power consumption is 46 mW with supply voltage of 3.3 V excluding output buffers.
