Abstract
A digital latch includes a latch circuit having first and second data inputs, first and second data outputs, and a clock signal input. The latch circuit has a first load value relative to a clock driver when data at the first and second data inputs is non-changing. The latch circuit has a second load value relative to a clock driver when data at the first and second data inputs is changing. The digital latch further includes a load compensation circuit operatively connected to the first and second data inputs of the latch circuit and to the first and second data outputs of the latch circuit. The load compensation circuit provides a first compensation load value upon the clock driver when data at the first and second data inputs is non-changing and provides a second compensation load value relative upon the clock driver when data at the first and second data inputs is changing such that a sum of the first load value and the first compensation load value equals a sum of the second load value and the second compensation load value.
