TLDR
In this paper, a method for tuning nano-scale analog-circuit designs in order to reduce random-device mismatches and optimize said design, where nanoscale devices potentially have large-scale process variations is presented.Abstract:
The invention discloses a method for tuning nano-scale analog-circuit designs in order to reduce random-device mismatches and optimize said design, where nano-scale devices potentially have large-scale process variations. The method includes providing a tunable circuit topology, wherein each nano-scale device comprises a single component or comprises multiple parallel components. Each component is decomposed into multiple discrete sub-components, wherein each said sub-component either operates in parallel with other like components to effectively operate like one bigger component. The sub-components are subjected to a dynamic-programming process to adaptively select the sub-components to be kept operational, while configuring the nonselected sub-components to be nonoperational, based on the measurement of at least one operational parameter.read more
