A 10-GHz Low Phase Noise Differential Colpitts CMOS VCO Using Transformer Coupling Technology

摘要：

We demonstrated a 10 GHz low phase noise differential Colpitts Voltage-Controlled Oscillator (VCO) utilizing TSMC 0.18 1m 1P6M CMOS process with transformer coupling technology. The transformer coupling approach not only reduces the phase noise but also improves the power consumption owing to the number of active devices can be reduced. The total power consumption of this VCO is 20mW and there is only 8mW power consumption in the oscillator core under lower supply voltages. By adding the buffers to the output terminal, it avoids the influence from the parasitic effects and also achieves a good performance in low phase noise.
