Abstract: A within-chip magnetic field control device is formed in proximity to a Josephson Junction (JJ) structure. The within-chip magnetic field control device includes wiring structures that are located laterally adjacent to the JJ structure. In some embodiments, the magnetic field control device also includes, in addition to the wiring structures, a conductive plate that is connected to the wiring structures and is located beneath the JJ structure. Use of electrical current through the wiring structures induces, either directly or indirectly, a magnetic field into the JJ structure. The strength of the field can be modulated by the amount of current passing through the wiring structures. The magnetic field can be turned off as needed by ceasing to allow current to flow through the wiring structures.

The circuit is provided is a high resolution, high linearity, low area, low power multiply—accumulate (MAC) unit to interface with a memory device for storing computation output results.

Abstract: A voltage controlled oscillator (VCO) circuit employing digital amplitude control of the output oscillating signal and method of operation. The digital control is provided by an analog to digital converter (ADC) element that is shared among many other operating blocks in a system. In a configuration, the oscillator current is obtained by implementing transistors in a linear region and controlling them digitally. The optimum amplitude detection is performed by measuring the DC voltage at the common mode nodes in the oscillator, and is realized using reduced time compared to an extensive frequency measurement over a long time window. The digital control is implemented using an on-chip regulator, and employs digital controls for adjusting the current consumption which leads to low on-chip area overhead, low cost, and a scalable implementation. In an implementation, a one-time code can be obtained for optimum phase noise operation when providing the digital amplitude control.
