Analog Characterization Module with Data Converter-Coupled Signal Reconfiguration

This paper provides quite a new approach for analog computing. This work proposes an analog characterization module to imitate (emulate) various analog components as essential technologies for analog reconfigurable system. This module converts an analog input signal into digital by an ADC, makes use of digital signal processing technologies to characterize the signal as expected, and outputs the analog signal converting by a DAC. Unlike a typical digital-assist, the module is used as a pseudo analog component. In this paper, we verify the feasibility of our idea with respect to DC operating characteristics as a resistance. In addition, we incorporate our analog characterization module into the feedback of opamp and clarify the cancellation the discretization noise.
