Abstract: PURPOSE:To provide the Josephson polarity switching type driving circuit capable of finely fabricating the circuit and speeding up the operation thereof. CONSTITUTION:When a current is injected from a signal input terminal (S1 or S2), since a current is injected to an SQUID loop while a superconduction critical current of the 2-junction SQUID loop is suppressed, drive voltage generating sections 1, 2 are in a voltage state, the signal current is injected to a driven line, and when a current is injected from an output terminal (O1 or O2) through the driven line 3 on the other hand, since the superconduction critical current of the 2-junction SQUID loop is not suppressed, the polarity changeover is attained by the operation of a drive voltage generating section to keep the superconducting state.

Title: Buffer circuit
Inventor: HAYAKAWA TATSUO
IPC: H03K19/00
Filed: 1981-01-12
Abstract: PURPOSE:To nearly eliminate a current, leaking to a substrate, which is characteristic to the PNP transistor (TR) of an IC by connecting the cathode and anode of a diode to the base and collector of the PNPTR of the IC. CONSTITUTION:Between the base and collector of a lateral PNP TRQ9, the cathode and anode d2 of a Schottky are connected. An input to an input terminal is supplied to the base of the TRQ9 directly and to the base of an NPNTRQ10 through a level converting circuit G3. Since a forward voltage drop across the diode D2 is less than that across PN junction, the TRQ9 is never saturated even if the TRQ10 turns off and the TRQ9 turns on. Therefore, the 2nd collector current Ic2 when the substrate of the TRQ9 is regarded as a collector is about 1/10 as great as the 1st collector current Ic1. Consequently, a current leaking to the substrate is decreased to the extent that it can be disregarded with comparison with a current leaking to the substrate when the diode D2 is not inserted.
