A LOG-Induced SSN-Tolerant Transceiver for On-Chip Interconnects in COG-Packaged Source Driver IC for TFT-LCD

Abstract

This brief presents a line-on-glass-induced simultaneous switching noise (SSN)-tolerant transceiver for on-chip interconnects in a chip-on-glass-packaged source driver IC for TFT-LCDs. An SSN compensator generates noise-sensitive bias voltages to maintain the bandwidth of a receiver. With each 10% noise of VDD and GND, the proposed circuit shows an eye width of 0.542 UI with a bit error rate (BER) of 10(-10) for 2-GB/s PRBS-7 while a conventional repeater shows an eye width of 0.132 UI with a BER of 4.62 x 10(-3) when +/-75-mV pp VDD and GND noises are injected.
