Abstract

In Josephson technology, the problem of punchthrough is well known. known. This problem occurs when the devices do not reset sufficiently fast as the power supply waveform goes to zero. In order to correct this problem, numerous techniques have been devised for introducing a "dwell time" when the waveform passes through zero. However, some of these approaches reduce the time available for the active duty cycle of the circuit. The circuit shown lengthens the active duty cycle without reducing the amount of dwell provided near the zero crossing.
