Frequently Asked Questions


1) Most foundries provide models that are not accurate for weak (sub-threshold) and moderate inversion, or other ultra-low-power considerations. How do you solve this issue?


2) Why do you sometimes still work with 0.35, 0.60, etc. microns technologies?


3) What type of A/Ds and D/As have you developed?


4) Have you done "proof-of-concept" discrete-components designs prior to ASIC implementation?


1) Most foundries provide models that are not accurate for weak (sub-threshold) and moderate inversion, or other ultra-low-power considerations. How do you solve this issue?

Foundries generally give you BSIM models. In most cases they provide good fitting in weak and strong inversion but are not accurate when describing moderate inversion. Besides, the BSIM model is of not much help to the custom analog designer when sizing transistors due to the lack of physical meaning in many of its parameters. NanoWattICs knows how to extract EKV and/or ACM parameters from such BSIM models to provide an accurate and continuous model from weak to strong inversion. The ACM model, for example, is composed of very simple expressions, valid for any inversion level, conserves charge and preserves the source-drain symmetry of the transistor.

2) Why do you sometimes still work with 0.35, 0.60, etc. microns technologies?

Safety-critical applications (i.e. medical, aerospace, etc.) generally require selecting a mature technology instead of the latest tens-of-nanometers one in order to achieve the required reliability. Additional factors that influence the technology selection are: maximum tolerable voltages, availability of extensions (e.g. high voltage), economical aspects. NanoWattICs works very closely with the customer in the definition of the most suitable technology for a particular project.

3) What type of A/Ds and D/As have you developed?

We concentrate on low-speed/ultra-low-power: 1 MSPS range but consuming only a few microwatts.

4) Have you done "proof-of-concept" discrete-components designs prior to ASIC implementation?

Yes. We have developed discrete-components prototypes for customers who lack expertise in electronic design so they can evaluate their idea prior to implementing it on an ASIC.
