Abstract :
A general formulation for switched-capacitor or continuous-time filter architectures is used to make a comparison of the properties of the various architectures within a common framework. The performance parameters considered are the sensitivity of response to component parameter variations and the extent to which nodal voltage scaling in order to maximize signal handling capability can be applied. Some examples are presented and discussed
