Superconducting FET circuits for analogue VLSI signal processing

CMOSuFET (complementary metal - oxide - superconductor field-effect transistor) discrete-time current-mode (DM) and continuous-time current-mode (CM) circuits for an analogue VLSI (very-large-scale-integrated) signal processing system are described. A family of modules - a simple sampled-data current memory circuit, a current delay circuit, a current integrator, a continuous-time current mirror, and an amplifier - are presented. Their main advantage lies in the very high frequency response, and very low power dissipation. The circuits have extensive development potential for high-performance analogue VLSI signal processing systems.
