Signal return path discontinuities, parasitic inductance and impedance mismatch within interconnects are major factors that contribute to degraded high-speed signal quality in threedimensional (3D) integrated circuits and systems. In this paper, we apply an alternate power delivery method and a novel I/O signaling scheme to a 3D system to address these issues. Two test vehicles made of stacked PCBs that resemble 3D integrated systems will be presented. One test vehicle is designed based on our proposed approach while the other is based on the conventional power delivery network design. The signal integrity and power supply noise performance will be shown in both simulated environment and actual test measurement. At data rates up to 3Gbps, our proposed design produces higher signal quality than the conventional design with better eye height, lower timing jitter, and lower power supply noise.

“…Using the PTL-based PDN, both the power and signal transmission line can be referenced to a common ground plane so that a continuous return current path can be achieved and the cavity resonance effect can be removed. However, using PTL introduces some issues, namely 1) output data-dependent dc drop on the PDN due to the terminating resistance, 2) mismatch effect between the power transmission line and terminating resistor, and 3) increased line congestion [5]. Also, power consumption needs to be considered.…”

With the trend toward higher operating frequencies, the simultaneous switching noise (SSN) problem is being aggravated. The required noise tolerance for testing scenarios is more demanding so that it raises the importance of control over SSN in the interface board between a device under test and an automatic test equipment. Low noise is especially important when testing mixed-signal devices, in which noisy digital circuits and noise-sensitive analog circuits share a power delivery network (PDN). To prevent noise coupling between circuits and provide low-noise testing environment, the method of supplying power through transmission lines instead of a voltage plane can be employed. The power transmission line (PTL) not only provides isolation between circuits, but also removes the voltage plane along with its adverse effects such as the cavity resonance and the return path discontinuity. In this paper, the first demonstration of a Constant Current Power Transmission Line (CCPTL)-based single-ended signaling scheme is presented. The measurement results show that the CCPTL-based PDN improves the eye quality at the receiver side as compared to the power-plane-based PDN.Index Terms -Low noise, simultaneous switching noise, power delivery network, power transmission line.

To control SSN in the power delivery network, providing power through transmission line instead of voltage plane can lead to better performance. Several issues arise when the power transmis sion line is used in a real environment. Amongst them, a practical scheme presented in this paper focuses on supplying a stable voltage to the common power supply node of multiple I10s switching simultaneously. The simulation results show that the newly suggested scheme generates power supply noise-free eye opening and consumes almost the same amount of power as the conventional power plane scheme.
