Interconnect structures for minimizing clock and output timing skews in a high speed current steering DAC
Abstract:
A digital-to-analog converter (DAC) system includes a DAC and a clock interconnect module. The DAC includes a plurality of segments and a plurality of drivers. Each of the plurality of segments receives driver signals from a respective one of the plurality of drivers and generates a positive output and a negative output based on the driver signals. Each of the plurality of drivers receives a respective one of a plurality of clock signals and outputs the driver signals based on the respective one of the plurality of clock signals. The clock interconnect module includes an interconnect loop. A clock input is connected to a first portion of the interconnect loop and the plurality of clock signals are output from a second portion of the interconnect loop connected to the plurality of drivers. An output interconnect module receives the positive outputs and the negative outputs generates a differential output signal.
