Abstract
The present invention provides an array of tunable, injection-locking oscillators which are scalable to higher frequencies and measure the entire relevant frequency space simultaneously. The scalable, highly-parallelized, adaptive receiver architecture uses arrays of tunable, injection-locking nonlinear oscillator rings for broad spectrum RF analysis. Three separate and different microelectronic circuit configurations, each having a different type of readout, are described. The embodiments are designed to be incorporated as a subsystem in any type of powered system in which a fast image of the broader spectrum is valuable, when no information about the location of signals in the frequency space is predictable or forthcoming.
