Abstract:
|
The technique of Body Bias to control threshold voltage is especially suited for FDSOI technology. Given very low voltage energy sources, it is interesting to compensate the associated loss of speed by applying on-chip generated forward body bias (FBB). There are several challenges involved in the use of this new technology with such low input voltages. |
Abstract:

Electronics circuits powered at near-threshold voltages (ultra-low voltage designs) are desirable for their low power consumption. However, the performance at such voltage supply is degraded. The application of forward body bias to the circuit can counteract the performance loss. FDSOI is a suitable technology to these techniques, due to its high range of body bias voltages. To generate that body bias voltages, positive and negative, charge pumps circuits are designed to be integrated on the chip. This thesis studies the main challenges on the design of such circuits operating at 300 mV to reach voltages of ± 1 V with power consumption lower than 1 µW and how to model it for layout process. In addition, a control circuit is also designed to provide different intermediate body bias voltage. |
