- 論文の詳細を見る
To develop MB DC-SQUIDs as magnetically controlled high speed logic devices, the magnetic modulation of the critical current in these devices is analyzed using a simplified equivalent circuit and equations of state, where the sinusoidal or piecewise linearized current phase relation is assumed. It has been found that the minimal critical current can be expressed in terms of a single characteristic parameter of the SQUID, and this parameter and the magnetic sensitivity are evaluated for two typical configulations, planar and layer, suitable for integrated circuits.The feasiblity of using them as logic devices are discussed.The magnetic sensitivity of planar MB SQUIDs is compared with experimental data, and is found to be in good agreement.The nonlatching operation of the device is confirmed experimentally.
