Abstract:
The proposed single-ended transmitter for memory interfaces is an impedance-matched transmitter that utilizes a single ring-oscillator-based time-domain ZQ calibration. This ZQ calibration technique eliminates the offsets by using a gain-controlled ring oscillator with late-case forcing, resulting in low maximum/average error rates. The transmitter incorporates a phase equalization method to …
