Abstract :
Summary form only given. MOSFETs built on SOI have yielded superior performance in RF (>1 GHz) applications mainly because of the inherent device isolation afforded by the underlying oxide. However, the floating-body (FB) non-fully depleted (NFD) SOI MOSFET has not been seriously considered as an option for analog circuits since it suffers from the kink effect. In this paper, we present a novel approach to ensure kink-free operation of FB-NFD/SOI analog circuits, using it in the design of a 10-bit current-steering D-A Converter (DAC). SOISPICE-4.4, with its device models upgraded and refined for high-frequency analog applications, is used to simulate the DAC and verify the design approach
