Taped-out in October 2016 this test-chip was designed to explore on chip wireless communication in the mm-wave frequency band. The chip was fabricated in an AMS 0.35um technology and incorporates two meander monopole antennas (which can be observed in the lower left and right corners of the die in Figure 1, see below), in addition to a range of other digital circuits.


ECStest2016 Test Chip

The chip was returned in May 2017 and has undergone rigorous testing for use in wireless on-chip clock distribution.

On-Chip Antenna Performance
