摘要： An embodiment provides power (having low voltage, high current, and high current density) to ultra low voltage non-CMOS based devices using a distributed capacitor that is integrated onto the same chip as the non-CMOS devices. For example, an embodiment provides a spin logic gate adjacent dielectric material and first and second plates of a capacitor. The capacitor discharges low voltage/high current to the spin logic gate using a step down switched mode power supply that charges numerous capacitors during one clock cycle (using a switching element configured in a first orientation) and discharges power from the capacitors during the opposite clock cycle (using the switching element configured in a second orientation). The capacitors discharge the current out of plane and to the spin logic devices without having to traverse long power dissipating interconnect paths. Other embodiments are described herein.

摘要： An optical modulator includes a ring resonator with a waveguide adjacent to and optically coupled to the micro-ring resonator. A p-i-n junction is formed about the ring resonator. An optional additional doped region may be formed opposite the waveguide from the ring resonator and when combined with the p-i-n junction forms a nearly closed p-i-n junction about the ring resonator. The ring resonator may be a silicon micro-ring resonator. Multiple different resonant frequency resonators may be coupled to the waveguide along with different detectors to multiplex light on the waveguide. The spectrum of the resonator may be controlled by an applied voltage. A prepulsing device may be used to enhance electrical transitions to enhance the speed of the modulator.

摘要： Embodiments include a test circuit to test one or more magnetic tunnel junctions (MTJs) of a magnetic random access memory (MRAM). The test circuit may measure a 1/f noise of the MTJ in the time domain, and determine a power spectral density (PSD) of the 1/f noise. The test circuit may estimate one or more parameters of the MTJ and/or MRAM based on the PSD. For example, the test circuit may determine a noise parameter, such as a Hooge alpha parameter, based on the PSD, and may estimate the one or more parameters of the MTJ and/or MRAM based on the 1/f parameter. Other embodiments may be described and claimed.
