Abstract:
A circuit includes a first differential ring-type oscillator, a second differential ring-type oscillator, and a coupling structure. The coupling structure capacitively couples the first and second differential ring-type oscillators. A method of synchronizing the first and second differential ring-type oscillators is also disclosed.
