Abstract
A DAC for converting a sequence of digital words into a corresponding analog signal. The DAC includes: a thermometer code generator fed by the sequence of digital words for providing N parallel outputs, each one of the outputs having one of two discrete levels; and an amplifier section having a plurality of N amplifiers, each one of the N amplifiers being fed by a different one of the M outputs. Each one of the amplifiers is driven into saturation in response to one of the two discrete levels or pinched-off in response to the other one of the two discrete levels. A combiner sums outputs of the N amplifiers producing a sequence of analog signals having levels related to the decimal values of the sequence of the digital words. An interconnection network interleaves connections between the thermometer code generator and the plurality of amplifier sections.
