Simultaneous switching noise (SSN) occurs when clock synchronized core circuits switch simultaneously. Furthermore, a huge amount of the SSN generated by simultaneous switching current (SSC) with high power distribution network (PDN) impedance at anti-resonance can cause electromagnetic interference (EMI) problems and logic failure. In multi-core processors, the spectrum of SSC is varied by power...
In this paper, we first propose and demonstrate an interposer-level wireless power transfer (WPT) scheme to reduce the number of wired power supply interconnections for high-density silicon interposer-based 2.5-D and 3-D integrated circuits (2.5-D and 3-D ICs). We first suggest the concept of an active silicon interposer, fabricate it with active circuits for WPT, and finally proved its WPT operation...
In this paper, a new on-interposer passive equalizer was proposed for chip-to-chip high-speed serial data transmission. It is a coil-shaped shunt metal line and embedded on a ground plane to maximize channel routability. Since the proposed equalizer is based on the fine pitch design rules of silicon interposer, it can be integrated in a small area. Equalizing method is based on a high pass filter...
