AI Technical Summary
Traditional series resonant voltage-controlled oscillators operate at lower frequencies and suffer from deteriorating phase noise at high frequencies, while multi-core parallel resonant voltage-controlled oscillators increase chip area and power consumption, and have complex power management.
A windmill-type coupled series resonant voltage-controlled oscillator based on an F-type inductor network is adopted. Four oscillator cores are arranged in rotational symmetry. The F-type inductor network and inverter units are connected in series. Combined with a frequency tuning unit and parallel inductors, the coupling between stages within the core is enhanced and the influence of parasitic capacitance is reduced. Inductor voltage divider technology is used to control the gate voltage swing.
It achieves stable oscillation at 40 GHz, reduces phase noise, enhances robustness between core stages, avoids the negative impact of parasitic capacitance on frequency, and maintains low power consumption under standard supply voltage.
