Performance optimization of High Speed DACs using DSP

DSP techniques that enhance the effective resolution of digital-to-analog converters (DACs) are presented. First, DACs that are limited by physical number of bits (PNOB) are addressed. An improved digital-resolution-enhancer (DRE) algorithm, which incorporates an optimized non-uniform quantization scheme is analytically analyzed and experimentally demonstrated. Improvement of up to 8 dB is shown, ...
