Opamp Topologies for Oversampled Converters,. Several authors have studied the effect of the finite slew rate on the modulator performance. However, all of them assumed a simple slew rate formula based on class A opamps. Since any practical opamp can not supply infinitely large current, the transient process is more or less slew-rate limited

Optimal Design of Opamps for Oversampled Modulators, The sharp peaks in both curves are the result of tones [Candy and Benjamin, 1981]. Previous research [Medeiro and Perez-Verdu, 1994] has shown that some amount of harmonic distortion is inevitable. Additionally, it has been shown that the amount of distortion is input signal dependent. While a perf

Opamp Topologies for Oversampled Converters,re studied extensively[Medeirand Perez-Verdu, 1994, Boser and Wooley,1988, Hauser and Broderson, 1986, Bishop et al., 1990]. These studies are carried out without assuming any particular opamp topology. Nonidealities such as finite gain, finite slew rate and finite gain bandwidth were incorporated i
