per-channel data-rates and energy efficiency to meet projected system bandwidth demands. These constraints necessitate the design of ultra-low-power serial-link transmitters that can efficiently incorporate equalization to compensate for channel losses, while enabling fast power-state transitioning to leverage dynamic power scaling. In this work, a scalable-data-rate voltage-mode transmitter is presented that introduces two main innovations. First, an impedance-modulated 2-tap equalizer is adopted that employs analog control of the equalizer taps, thereby obviating output driver segmentation. Second, fast power-state transitioning is achieved using a replica-biased voltage regulator to power the output stages of multiple
