Low-Phase Noise Clock Distribution Network Using Rotary Traveling-Wave Oscillators and Built-In Self-Test Phase Tuning Technique


This brief describes a built-in self-test (BIST) technique used to verify and tune the timing integrity of a clock distribution system implemented with injection-locked rotary traveling-wave oscillators (RTWOs). The die is fabricated in a 130-nm CMOS process and occupies 4.4 mm × 2.25 mm and is limited by the outer diameter of the RTWOs, leaving… (More)
