Abstract

See full text

A circuit component that is adjustable at run time and a method of designing the circuit are disclosed. The component contains a hierarchy of recursive levels in which a bottom level is a compound element made from two connected simple elements, and each higher level contains two compound elements connected in the same fashion. The described circuit allows for a large number of available values of the component value to be arranged in a logarithmic fashion rather than a linear one as in the prior art, thus generally reducing errors between any desired value for the component and the available values. In addition, such compound elements reduce the power dissipated by the analog element and the susceptibility to noise as compared to prior art adjustable components without adversely affecting the overall gain of the circuit.
