Abstract

The dynamic threshold characteristics of Josephson-junction circuits operated as fast signal detectors have been simulated for a wide range of load conditions, pulse widths, and pulse amplitudes. The simulations have been carried out using the familiar resistively and capacitively shunted junction model and a modified version of an approximate Werthamer model for the Josephson junctions. Approximation formulas for the dynamic threshold characteristics are given, and a readout circuitry for inductively shunted sampling gates is presented.<>
