Design of a 10 GHz Ring Oscillator for PDK verification

In this work we developed a set of a 10 GHz Ring Oscillators for the purpose of verifying the accuracy of a CMOS foundrypsilas design tools. The project involves front end to back end design, to tapeout. After fabrication of the chip was completed, measurements were performed to test the accuracy of the oscillators. This test chip was used to verify Silterrapsilas PDK (Process Design Kit). Four different oscillator circuits were fabricated. The results show excellent agreement between simulated and measured gate delay.
