An overview of circuits and devices research on SOI technology for analog/mixed-signal systems

SOI technology has become the commercial technology of choice for both high performance and low power digital applications. By comparison, analog development in SOI is still in its infancy. To help emphasize analog/mixed-signal opportunities in SOI, both for circuits and new devices, this paper provides a sampling of the SOI research at the University of Tennessee. Circuit highlights include an operational amplifier with automatic offset cancellation, a VCO-based ADC, and body-driven analog circuits. The G⁴-FET, a four-gate transistor in SOI, is introduced. Floating-gate devices on SOI are also presented, including their application to post-process trimmable analog circuits.
