A third order sigma-delta modulator comprises a first summing unit for receiving an input signal, a first integrator network connected to an output of the first summing unit, a second integrator network for receiving an output of the first integrator network, a second summing unit connected to an output of the second integrator network, a third integrator network connected to an output of the second summing unit, and a feed-forward path from the output of the first integrator network to an input of the second summing unit.
