Simultaneous switching noise is a detrimental issue in high speed digital systems. In this paper, we utilize power transmission line based design and current steering to minimize power supply noise, eye height and jitter penalties.
This paper proposes an effective approach to suppress vertical electromagnetic (EM) coupling in multilayer packages operating at GHz frequencies. In the case of packages with embedded actives where there are large apertures (die sized) in the metal planes and cavities in dielectric layers to accommodate the chips, the effect of EM field coupling is significant. The method involves EM band-gap structures...
Return path discontinuities (RPDs) cause the coupling between signal lines and the power delivery network, resulting in power supply noise and reduced timing and voltage margins at high speed. Prior work focused at reducing the RPD effect, usually through the use of power planes and decoupling capacitors. A new approach to address this issue replaces the plane structure with power transmission lines...
Power integrity has become an indispensable part to ensure signal integrity in high-speed systems. Simultaneous switching noise (SSN) in the power delivery network (PDN) is now one of major factors to place the limit on the noise margin for off-chip communication so that a great emphasis is being placed on controlling SSN. A power transmission line (PTL) has been suggested as a new PDN design to achieve...
Due to the increasing operating frequency and power density, more current is being drawn from the power delivery network (PDN). For off-chip signaling, the drawn current flows through the signal transmission line outside the chip, and induces a return current on the reference plane. The power planes cause return path discontinuity (RPD), which induces power noise and coupling between the signal distribution...
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...
