Abstract
Circuitry and method for digital-to-analog current signal conversion with phase interpolation. For an n-bit digital-to-analog converter (DAC), the number 2n control bits normally required can be reduced to 2(n-1) by jointly controlling pairs of the current sources with one of the 2(n-1) current control bits and inverses of two other ones of the 2(n-1) current control bits.
