摘要： A Josephson junction transmission line (50) for transmitting single flux quantum pulses. The transmission line (50) includes a current source (53), a plurality of isolation inductors (52, 54) electrically coupled in series along the transmission line (50), and a plurality of Josephson junction circuits (60, 70) electrically coupled in parallel along the transmission line (50). Each of the Josephson junction circuits (60, 70) includes only a Josephson junction (62, 72) and a parasitic inductor (64, 74) coupled in series. The Josephson junction circuits (60, 70) do not include a damping resistor in order to reduce timing uncertainty and to enhance propagation speed.

摘要： A transconductance cell has first and second transistors, each transistor having a control terminal and first and second terminals. A signal is output from the second transistor in response to a voltage input applied to the control terminal of the first transistor. The transconductance cell includes a linear element coupled between the first terminal of the first transistor and the first terminal of the second transistor. A tank circuit is coupled between a reference potential and a node between the linear element and the first terminal of the second transistor.

摘要： An electronic power conversion circuit includes cryogenically cooled MOSFET power switching devices arranged in a switch-mode configuration and responsive to control signals for reducing capacitive discharge and commutation losses in the circuit by controlling the period between switch-on and switch-off time (i.e., “deadtime”) of the MOSFET devices. When one of the MOSFET devices of the circuit is switched off, the opposing MOSFET, after the short deadtime period, is switched on to serve as a commutating device rather, than the opposing MOSFET's intrinsic drain-source diode. The power conversion circuit may include a half-bridge circuit or combinations thereof.

摘要： The problem of the disclosed technology is as follows. Although a single flux quantum circuit can fabricate a high-speed sequential circuit with ease, the initialization of the circuit is required for guaranteeing the normal operation of the circuit. However, a prior-art circuit has no initializing function, or requires the restructuring of another logic system. For solving the foregoing problem, one Josephson junction is inserted to a flux quantum storage inductor constituting the existing logic circuit, so that a pulse for performing the circuit initialization is injected to the connection point by means of a comparator.

摘要： In integrators which integrate the analog photocurrent of a photodiode (PD), the amplification-bandwidth product is relatively small on account of the parallel parasitic capacitance (Cp) of the photodiode (PD). However, in a design with a switched capacitor (C1), the bandwidth and at the same time the DC amplification must be large, so as to assure the integrator function even at low frequencies. So as to fulfill both of these mutually contradictory requirements for large bandwidth and high DC amplification, a reference voltage (V1) is present at a voltage divider that includes a resistor (R2) and a circuit section (R1) connected in series thereto, as well as at the photodiode (PD). The connection point of the voltage divider is connected to the inverting input of the transconductance amplifier (V). In a preferred embodiment, the circuit section (R1) is realized as a switched capacitor (C1), and the resistance (R2) is realized as an MOS transistor (T1). As an integrated switching circuit, the invention is especially suited for sigma-delta-analog converters.
