Microelectronics

Synopsis

This site centralizes all my projects in the microelectronics field.
My abrupt shifting of research focus to the digital microelectronics field required a new presentation format. So I created this site. In this context the old Tube World site that originally contained my microelectronics projects becomes obsolete.
The microelectronics section will be archived and at some point its content will be completely moved here.
