Abstract
Embodiments of the present invention related to a neuromimetic circuit including a transmitter circuit to receive the threshold signal from a superconducting optoelectronic neuron and convert the small current pulse to a voltage pulse sufficient to produce light from a semiconductor diode. This light is the signal used to communicate between neurons in the network. The transmitter circuit in accordance with the present invention includes an amplifier chain that comprises two Josephson junctions, a superconducting thin-film current-gated current amplifier, and a superconducting thin-film current-gated voltage amplifier. The transmitter circuit in accordance with the present invention enable an amplification sequence that allows neuronal firing of about 20 MHz with power density sufficiently low to be cooled with standardHe cryogenic systems operating at 4.2 K.
