  • Apparatus and method for introducing a controllable delay to an input signal
    Patent number: 8558287
    Abstract: 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;
