摘要： Artificial neuron apparatus includes first and second resistive memory cells. The first resistive memory cell is connected in first circuitry having a first input and output. The second resistive memory cell is connected in second circuitry having a second input and output. The first and second circuitry are operable in alternating read and write phases to apply a programming current to their respective memory cells on receipt of excitatory and inhibitory neuron input signals, respectively. During the write phase, resistance of the respective cells is changed in response to successive excitatory and inhibitory neuron input signals. During the read phase, a read current is applied to their respective cells to produce first and second measurement signals, respectively. An output circuit connected to the first and second outputs produces a neuron output signal at a neuron output when a difference between the first and second measurement signals traverses a threshold.

摘要： Artificial neuron apparatus includes a resistive memory cell connected in an input circuit having a neuron input, for receiving neuron input signals, and a current source for supplying a read current to the cell. The input circuit is selectively configurable in response to a set of control signals, defining alternating read and write phases of operation, to apply the read current to the cell during the read phase and to apply a programming current to the cell, for programming cell resistance, on receipt of a neuron input signal during the write phase. The cell resistance is progressively changed from a first state to a second state in response to successive neuron input signals. The apparatus further includes an output circuit comprising a neuron output and a digital latch which is connected to the input circuit for receiving a measurement signal dependent on cell resistance.

摘要： A novel and useful THz radiation detector comprising a suspended wideband planar skirt antenna for achieving low thermal mass and high electrical performance. The antenna comprises only the perimeter or “skirt” of the antenna. The antenna has multiple loops where each loop comprises a conductor that covers the perimeter or skirt and includes multiple inner and outer arms. The total length of each loop has a length substantially one wavelength. One or more ports or load impedances are connected at the center of the antenna and shared by one or more loops. A thermal sensor detects the heat generated in the load resister and converts the heat energy to an electrical signal which is transmitted to read out circuitry via signal lines that run together with a holding arm. The holding arm functions as both a path for the read out signals as well as providing mechanical support for and effectively suspending the antenna.
