Abstract
This paper presents a power-supply noise canceller (PSNC) for current-steering DAC for high-speed and high-throughput wireless communication systems. Proposed PSNC effectively detects power-supply noise (PSN) and controls the current sources so that PSN would be removed at the output signal. The fabricated 2.24-GHz, 6-bit DAC has demonstrated a maximum of 8.4-dB PSN-reduction. Also, this DAC achieved a spurious-free dynamic-range (SFDR) of larger than 35 dB over full Nyquist frequency.
