On-chip inductance extraction and analysis is becoming increasing critical. Inductance extraction can be difficult, cumbersome and impractical on large designs as inductance depends on the current return path — which is typically unknown prior to extracting and simulating the circuit model. In this paper, we propose a new circuit element, K, to model inductance effects, at the same time being e...

An analytical procedure for the calculation of the inductance of planar zig-zag spiral inductors is proposed. The procedure is based on the partial inductance concept and models the inductor as a series of a number of parts. The self-inductance of each individual part, which has the shape of a parallelogram, and the mutual inductance between any two parts of the inductor are determined. The ind...

Direct measurements of propagation delay of single-fluxquantum (SFQ) circuits were performed using SFQ double-oscillator time-to-digital converters. The propagation delay of several SFQ logic gates in our cell library named CONNECT were measured in picosecond resolution. Small discrepancy in the propagation delay of picosecond level was observed between measurement and circuit simulation result...

The phase shift full bridge (PSFB) converter allows high efficiency power conversion at high frequencies through zero voltage switching (ZVS); the parasitic drain-to-source capacitance of the MOSFET is discharged by a resonant inductance before the switch is gated resulting in near zero turn-on switching losses. Typically, an extra inductance is added to the leakage inductance of a transformer ...

In high power converter design, low-inductance busbar connecting DC capacitors and power devices is the main concern to improve the quality of the whole power electronics system. There are several facts which affect the stray inductance of bridge arm. This paper mainly analyzes the influence of DC-power layout on the stray inductance taking a subway traction converter as example. The Psim9.0 so...
