US Patent 7312737 Bandwidth enhancement by time interleaving multiple digital to analog converters

A digital-to-analog converting system for producing an interleaved analog signal with enhanced bandwidth includes a first digital-to-analog converter for receiving a first digital data stream and converting the first digital data stream to a first analog signal and a second digital-to-analog converter for receiving a second digital data stream and converting the second digital data stream to a second analog signal. The digital-to-analog converting system is clocked by a clock signal having a clock period, and further includes first timing circuitry for receiving the first analog signal and outputting the first analog signal for a first half of the clock period and second timing circuitry for receiving the second analog signal and outputting the second analog signal for a second half of the clock period to produce the interleaved analog signal.
