  • Method and apparatus for reducing input differential pairs for digital-to-analog converter voltage interpolation amplifier
    Patent number: 8248287
    Abstract: For voltage interpolation amplifiers used in digital-to-analog converter architecture, the number of input differential pairs required by the voltage interpolation amplifier may be reduced such that an N-bit voltage interpolation amplifier comprises N+1 input differential pairs connected through a resistor attenuation network to provide a binary-weighted effective transconductance. In comparison to conventional voltage interpolation amplifier designs, the number of input differential pairs and power consumed by the circuit is significantly reduced, thereby creating a more area- and power-efficient voltage interpolation amplifier.
