A MASH modulator. The MASH modulator receives a fractional input value, generates an integer output value, and comprises three cascaded first order sigma delta modulators (SDMS) each comprising an accumulator, a plurality of first multipliers, a second multiplier, a first adder, and a second adder. Each of the first multipliers is coupled to a corresponding accumulator. The first adder receives the fractional input value. The second multiplier is coupled between the first adder and the cascaded first order sigma delta modulators. The second adder is coupled to the cascaded first order sigma delta modulators to generate the integer output value.
