2023年12月15日 · Current compensation mechanism of the FJTL is investigated, and a formula for compensating current ΔI is derived. A method is proposed to enhance the bias margin of ERSFQ circuits and reduce the size of FJTL by applying feeding pulses into the FJTL.

Abstract: Energy-efficient rapid single flux quantum circuits having zero static power dissipation require a feeding Josephson junction transmission line (FJTL) to stabilize the power bus voltage.

2023年12月15日 · This study investigates the current compensation mechanism of the FJTL and derives a formula for the compensating current ΔI in the main logic circuit by each pulse input to the FJTL. Based on the formula, a method is proposed to enhance the bias margin of ERSFQ circuits while reducing the size of FJTL by applying feeding pulses into the FJTL.

2023年1月27日 · Any ERSFQ circuit requires a feeding Josephson transmission line (FJTL), a relatively large active transmission line, which serves as an accurate voltage source. For proper operation, the FJTL needs to be continuously pumped at a frequency that is equal to or higher than the highest clock frequency of the ERSFQ circuit.

2017年12月26日 · FJTL establishes a robust voltage reference for the bias bus of an ERSFQ circuit, and improves the margins of operation by supplying additional or receiving excess bias current.

2019年3月7日 · To optimize the design of the feeding Josephson transmission line (FJTL) required by the ERSFQ variant, we compared different power grid structures and types of FJTLs. Using an 8-bit counter with P2S interface as a device under test, we also investigated the effect of FJTL's size on the bias margins.

2021年5月29日 · The clock line is connected to a structure called a feeding JTL (FJTL) to increase both the stability of the voltage reference and the bias margins. A feeding JTL is schematically depicted in Fig. 4.19. A FJTL is a JTL consisting of multiple stages, where each stage is connected to the bias bus by a large inductor L B. This JTL is typically ...

2023年11月17日 · The ERSFQ bias scheme requires multiple circuit elements—current limiting Josephson junctions, bias inductors, and feeding Josephson transmission lines (FJTL). In this chapter, parameter guidelines and design techniques for ERSFQ circuits are presented.

2023年11月1日 · Any ERSFQ circuit requires a feeding Josephson transmission line (FJTL), a relatively large active transmission line, which serves as an accurate voltage source.
