Abstract:
1. An apparatus comprising: a first oscillator array including a first plurality of N nonlinear oscillators each having an oscillator input and an oscillator output and each having a summer operably coupled to provide a summed oscillator input, said first oscillator array also including a first intra coupling network to couple said oscillators so that each said oscillator output is coupled to at least one other said nonlinear oscillator in said first plurality of N nonlinear oscillators; a second oscillator array including a second plurality of N nonlinear oscillators each having an oscillator input and an oscillator output and each having a summer operably coupled to provide a summed oscillator input, said second oscillator array also including a second intra coupling network to couple said oscillators so that each said oscillator output is coupled to at least one other said nonlinear oscillator in said second plurality of N nonlinear oscillators; and an inter array coupling network coupling said oscillators of said first plurality of N nonlinear oscillators to said second plurality of N nonlinear oscillators so that each oscillator output of said first oscillator array is provided as an input to the respective said summer of each nonlinear oscillator of said second oscillator array and so that each oscillator output of said second oscillator array is provided as an input to the respective said summer of each nonlinear oscillator of said first oscillator array, wherein an oscillation frequency generated in one of said arrays generates a frequency-multiplied oscillation frequency in the other of said arrays that is substantially N times said oscillation frequency of said one array.
