摘要： A digital-to-analog converter supporting high speed operation is defined. The converter includes a plurality of sampler circuits in electrical communication with a digital signal source and a summation circuit in electrical communication with the plurality of sampler circuits. A sampler circuit of the plurality of sampler circuits is adapted to sample a bit of a plurality of bits from the digital signal source with a half-sinusoidal signal forming a sampled signal. The sampler may include a plurality of diodes and a sinusoidal signal source. The sinusoidal signal source toggles the plurality of diodes on and off thereby forming the sampled signal at a sampler output port. The summation circuit is adapted to combine the sampled signal from each of the plurality of sampler circuits to form an analog signal portion representative of the plurality of bits. Exemplary summation circuits include an R-2R resistance ladder and a Wilkinson power combiner.
