Single amplifier sigma delta modulator with input feedforward
2006 (Engelska)Konferensbidrag, Publicerat paper (Refereegranskat)
Abstract [en]
It has recently become very popular to feedforward the input signal in wideband delta-sigma modulators, so that the integrators only process quantization errors. The advantage is that the actual signal is not distorted by op-amp and integrator nonlinearities. The paper applies this technique to single amplifier based sigma delta modulator in both analog and digital way. Their characteristic has been analyzed and simulation results are given which show the improved performance.
