Abstract :
Existing proposals for high temperature superconductor analog to digital converter (ADC) circuits suffer performance penalties because of the difficulty of fabricating devices with small and controlled inductances. The design of a quasi-one junction SQUID (QOJS) comparator for a high-T/sub c/ flash ADC is proposed and discussed. The inductances are calculated with the help of a three-dimensional field calculation program, and simulations on the QOJS-comparator are performed using a SPICE-type simulation program.<>
