Abstract

A compact energy-efficient 16-QAM wireline transceiver with carrier synchronization and threshold calibration is proposed to leverage high-density fine-pitch interconnects. Utilizing frequency-division multiplexing, the transceiver transfers four-bit data through one RF band to reduce intersymbol interferences. A forwarded clock is also transmitted through the same interconnect with the data simultaneously to enable low-power PVT-insensitive symbol clock recovery. A carrier synchronization algorithm is proposed to overcome nontrivial current and phase mismatches by including DC offset calibration and dedicated I/Q phase adjustments. Along with this carrier synchronization, a threshold calibration process is used for the transceiver to tolerate channel and circuit variations. The transceiver implemented in 16-nm FinFET occupies only 0.006-mm2 and achieves 10 Gb/s with 0.75-pJ/bit efficiency and
