Webb15 nov. 2000 · The current switching is used instead of voltage switching because current can be switched in and out of a circuit faster than voltage. The developed DAC employs two internal DACs. Each internal DAC has its own advantages. This DAC used thermometer code for three bit MSBs and R2R ladder for 5 bit LSBs. WebbAn 8-bit thermometer DAC would have 255 segments, and a 16-bit thermometer DAC would have 65,535 segments. This is a fast and highest precision DAC architecture but at the expense of requiring many components which, for practical implementations, fabrication requires high-density IC processes.
