Abstract
A method for making practically identical copies of a sampled current without relying on the matching of circuit elements (such as capacitors or transistors) is presented. Compact circuit realizations are discussed, leading to the generation of a family of analog function blocks for the creation, copying, and manipulation of current samples, all free from dependency on element matching. Applications of these circuits include signal processors and A/D (analog-to-digital) and D/A (digital-to-analog) convertors
