Abstract: In aspects of a low phase noise technique for use with a crystal oscillator, a bias control circuit sets a bias voltage on the gate of a first transistor needed to sink or source an amount of current corresponding to a sensed common mode signal. The sensed common mode signal is sensed with a common mode sense circuit that is coupled across two ports of the crystal oscillator, and current is provided by a current source. The bias voltage is set by a bias controller that uses a second transistor coupled to the common mode sense circuit and the first transistor.

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.

The second array includes an odd number, greater than one, of unidirectionally-coupled non-linear second array elements. The second array elements are unidirectionally-coupled in a direction opposite the coupling direction of the second array elements. The first array is configured to receive an input signal and down-convert the input signal. The second array is configured to receive the down-converted input signal, further down-convert the down-converted input signal, and output a down-converted output signal. The down-converted output signal is down-converted to a multiple of the frequency of the input signal proportional to the number of arrays of the system. The system may operate at frequencies greater than 1 GHz and may be contained in a microchip or on a printed circuit board.
