Measurement and Modelling of the High-Voltage Devices

  • Hussein Ballan
  • Michel Declercq


The measured static and dynamic characteristics of the SVX devices are presented first, where the high-voltage capabilities and the reliability aspects are pointed out through the measurement data. On the basis of these results, a first order modelling is then performed for both devices in order to allow further the simulation of high-voltage integrated circuits. It consists of two macro-models in which discrete devices are combined with a low-voltage transistor to model the behaviour of the lightly doped drains. Finally, the handling of high-voltage power supplies in a standard low-voltage CMOS process, necessitates the use of special layout precautions against parasitic effects. These precautions are discussed in the last part of this chapter.
