Abstract
Applications involving smart cards have rapidly emerged since a few
years. Up to now, chips are realized in conventional bulk technology.
But as the need for performance rises, alternative technologies must
be investigated. In this paper we study the feasibility of realizing
the blocks for a smart card chip in Silicon-On-Insulator (SOI)
technology. For most of the circuit blocks, SOI realization already
exists and may be adapted for this application. However, we identified
two circuits never fabricated in SOI: a charge pump and the random
number generator. The charge pump has been realized in SOI and tested.
A random signal source has also been realized. The circuit to create
random bits, based on this source, is exposed.
