An apparatus including a spin torque oscillator configured to receive an input electric current and to produce a radio frequency output signal; and a tunable current source for providing an input electric current to the spin torque oscillator.

Frequency synthesis

An apparatus including a first electrode portion configured to inject charge carriers; a second electrode portion configured to collect charge carriers and provide an output signal; a third electrode portion configured to collect charge carriers and provide an output signal; a monolithic semiconductor, providing a first channel for the transport of injected charge carriers between the first electrode portion and the second electrode portion and providing a second channel for the transport of injected charge carriers between the first electrode portion and the third electrode portion, wherein the first channel is configured such that a charge carrier injected at the first electrode portion will reach the second electrode portion via the first channel after a first transport time and the second channel is configured such that a charge carrier injected at the first electrode portion will reach the third electrode portion via the second channel after a second transport time greater than the first transport time; and at least one gate electrode coupled to the monolithic semiconductor configured to enable switching a route for charge carrier transport between at least the first channel and the second channel.

Apparatus and method for introducing a controllable delay to an input signal

Apparatus including a matrix; a plurality of magnetic particles distributed in at least a portion of the matrix; the matrix being configured to enable the plurality of magnetic particles to move position relative to one another, and at least a portion of the plurality of magnetic particles being configured to magnetically repel one or more adjacent magnetic particles.
