  As the Internet of Things (IOT) is growing rapidly, there is an emerging need
to facilitate development of IOT devices in the design cycle while optimized
performance is obtained in the field of operation. This paper develops
reconfiguration approaches that enable post-production adaptation of circuit
performance to enable RF IC re-use across different IOT applications. An
adaptable low noise amplifier is designed and fabricated in 130nm CMOS
technology to investigate the post-production reconfiguration concept. A
statistical model that relates circuit-level reconfiguration parameters to
circuit performances is generated by characterizing a limited number of
samples. This model is used to predict the performance parameters of the device
in the field. The estimation error for LNA performance parameters are obtained
in the simulation environment as well as chip measurements.
