Patent ID: 8552896

Claim:
A digital to analog converter, comprising: a source of a digital word having a decimal value n, where n is a decimal value between 0 and N; a thermometer code generator fed by the digital word for providing N parallel outputs m 1 -m N , each one of the outputs having one of two discrete levels, the number of the N parallel outputs having the same one of the two discrete levels being a function of the decimal value n, the outputs m 1 -m N having said same one of the two discrete levels successively increasing with increasing decimal value n; a plurality of multi-input load modulation amplifier sections, each one of the multi-input load modulation amplifier sections comprising: a plurality of amplifiers; and a load modulation network fed by outputs of the plurality of amplifiers; a interconnection network for interleaving connections between the thermometer code generator and the plurality of amplifier sections; and a combiner for summing outputs of the load modulation network of each one of the plurality of multi-input load modulation amplifier sections producing a sequence of analog signals having levels related to the decimal values of the sequence of the digital words.
