Abstract :
Magnetic feedback from a differential pair to the core of a cross-coupled oscillator reduces the effect of device losses, raising the oscillation frequency. Three prototypes using one-turn nested inductors and including on-chip downconversion mixers operate at 205 GHz, 240 GHz, and 300 GHz while drawing a power of 3.5 mW.
