Abstract :
The design of optimal dynamic range integrators that are meant as building blocks for optimal dynamic range analog continuous-time filters is discussed. A fundamental limit for the dynamic range of an integrator is given. This limit is a function of the supply voltage and the available amount of capacitance. It is shown how integrators are to be designed if this limit is to be reached. Different conventional integrator realizations are evaluated and optimized so that they can be compared to the fundamental limit. A design example of a filter with integrators that approach this limit is given
