A 10 Gb/s PAM-4 transmitter (TX) with a modulo-based equalization technique is presented. The proposed feed-forward Tomlinson-Harashima precoding (FF-THP) scheme takes advantage of both Tomlinson-Harashima precoding (THP) and feed-forward equalizatio

This paper presents the reference spur reduction techniques for an analog phase-locked loop (PLL). A simple leakage compensation loop is proposed, which cancels the leakage current of the PLL loop filter with a negligible power overhead. This leakage

This brief presents a programmable on-chip reference oscillator based on a slow-wave coplanar waveguide (S-CPW). The frequency is determined mainly by its geometric structure with floating stripes, thereby enjoying an advantage of being less sensitiv

This paper presents a transmit-side modulo-FIR equalizer (MFE) that is suitable for future high-throughput links. In a proposed PAM transceiver architecture, forward error correction (FEC) is employed to mitigate the BER degradation by the reduced SN

This brief presents a single-ended asymmetric push-pull inverter for driving a vertical-cavity surface-emitting laser (VCSEL). The proposed driver topology features less power dissipation compared with commonly used differential CML-based drivers. Co
