Claim 0:
1. A fully connected ring oscillator circuit comprising:
a plurality of first ring oscillator loops each extending along a first axis;
a plurality of second ring oscillator loops each extending along a second axis that is transverse to the first axis and intersecting the first ring oscillator loops;
a plurality of ring oscillators each comprising one of the first ring oscillator loops connected to one of the second ring oscillator loops through a strong coupling, each ring oscillator producing an oscillating signal; and
a plurality of coupled ring oscillators each comprising two of the ring oscillators connected to each other through a programmable weighted coupling block,
wherein each of the programmable weighted coupling blocks is configured to selectively apply to the corresponding coupled ring oscillator a positive weight coupling that drives the oscillating signals of the ring oscillators of the coupled ring oscillator toward oscillating in a same phase with each other, and a negative weight coupling that drives the oscillating signals of the ring oscillators of the coupled ring oscillator toward oscillating in an opposite phase with each other.
