Temperature Sensitivity and Compensation on a Reconfigurable Platform

This brief investigates temperature compensation techniques for circuits and systems on a reconfigurable platform. The work demonstrates use of large-scale reconfigurable system-on-chip for reducing the variability of circuits and systems compiled on a floating gate (FG)-based field-programmable analog array (FPAA). The work presents current and voltage reference which could help in reducing the variability caused due to changes in temperature. These references are standard blocks in the Scilab/Xcos environment, which could be easily compiled on the FPAA. An FG-based current reference is then used for biasing a second-order $G_{m}-C$ bandpass filter to demonstrate the compilation and usage of these voltage/current reference in a reconfigurable fabric. The large-scale FG FPAA presented here is fabricated in 350-nm CMOS process.
