Abstract
This paper presents an Rx only equalization (ROE) technique that eliminates all Tx equalizations to reduce power dissipation, circuit complexity, and cost. The proposed Rx consists of a CTLE, a 1-tap speculative FIR and 2-tap direct IIR DFE. A simpler Tx architecture owing to the ROE facilitates a wide bandwidth and energy efficient dual-mode (differential and single-ended) Tx operation. The proposed Tx consists of dual-mode 2-1 serializer/pre-drivers and main drivers. The transceiver was fabricated in a 65 nm CMOS technology. The Rx achieves BER < 10-12 over a -22 dB loss PCB channel at 32 Gb/s with 0.62 pJ/b energy efficiency, and occupies 0.024 mm2. The Tx has only 0.77 pJ/b and 0.40 pJ/b energy efficiency at 32 Gb/s in differential mode, and 32 Gb/s/pin in single-ended mode, respectively, and occupies only 0.002 mm2.
