I contributed to the project ARPIC (an academic platform for IC development). In March 2013 the first test chip realized through the ARPIC framework was sent to factory. The chip contained 20 functional blocks developed by teams within the three participating universities(the University ‘POLITEHNICA’ University of Bucharest, the “Technical University of Cluj-Napoca” and the ‘Gheorghe Asachi’ Technical University of Iasi.), comprising over 20 academics and postgraduate students.The test chip was implemented in the AMS H18 process, and occupied 9mm2, prepared for a 64-pin CQFP package.
I designed in Cadence a temperature sensor used for measuring the body temperature.This consists of two current sources which generate the current row with a switch to a current-frequency converter that generates a signal proportional to the rectangular frequency of an output current. The microcontroller will make decisions based on the application.If we measure the temperature,the microcontroller interprets the difference between the two frequencies generated by the input currents.
