Description: 10-b 50-MHz digital-to-analog (D/A) converter is presented
which is based on a dual-ladder resistor string. This approach
allows the linearity requirements to be met without the need for selection
or trimming. The D/A decoding scheme reduces the glitch energy, and
signal-dependent switch signals reduce high-frequency distortion. The
output buffer allows driving 1 V,,, to 75 Cl Platform: |
