SUPERCONDUCTING FET CIRCUITS FOR ANALOG VLSI SIGNAL-PROCESSING

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