Abstract
An improved write precompensation circuit. Eight phases from a PLL phase oscillator are received as inputs into a bank of four phase blenders ( ). The phase blenders ( ) output a 0%, 25%, 50%, or 75% interpolation to the adjacent phases. A multiplexer ( ) is then used to select which of the phase outputs is used for the write precompensation.
