A Compact On-interposer Passive Equalizer for Chip-to-chip High-speed Data Transmission

In this paper, a new compact on-interposer passive equalizer was proposed for chip-to-chip high-speed data transmission on the silicon-based on-interposer channel. The proposed equalizer uses the parasitic resistance and inductance of the coil-shaped on-interposer shunt metal line structure to produce the high-pass filter for loss compensation. This results in wide-band channel equalization and low power-consumption. Moreover, the compact coil-shaped structure of the proposed equalizer allows for wide I/O and high adjustability. The remarkable performance of the proposed compact on-interposer passive equalizer is successfully demonstrated by a frequency- and time-domain simulation of up to 10 Gbps.
