In conventional pipelined analog-to-digital converters (ADCs), it is common to employ digital-to-analog converters (DACs) in the ADC stages that use two-state switches or segments. A problem with this arrangement is that for each DAC state there is a noise contribution from each DAC switch, resulting from its current source. Here, however, a DAC is employed that uses three-state DAC switches, which reduces the noise contributions from the DAC switches' current sources and reduces the amount of area used. |
