WP1 WP2 WP3 WP4 WP5 COORDINATOR WORK PACKAGE LDR RESEARCHER ACEOLE MID TERM REVIEW CERN 3 RD AUGUST 2010 Phase Locked Loop (PLL) Measures phase difference of two signals Comprises, mainly, the following blocks: Phase Detector, Loop Filter, Voltage-Controlled Oscillator Frequency Divider – dividing factor of 2 PLL Operation Modes 11 Stand-alone operation The circuit should be low noise and insensitive to Process-Voltage- Temperature (PVT). The central frequency is generated applying a voltage to the VCXO

WP1 WP2 WP3 WP4 WP5 COORDINATOR WORK PACKAGE LDR RESEARCHER ACEOLE MID TERM REVIEW CERN 3 RD AUGUST 2010 On the Project – Design of a very low-phase noise PLL/oscillator with Built-In Self Test capabilities. On testing time and cost – can be reduced as test circuitry is implemented on-chip On work’s methodology – a top-down analysis, with the development of macro simulation algorithms, provides an improved integrated circuits’ design method. On my career – Interaction with experts at CERN, FEUP (associated partner) and conferences, has increased my knowledge as well as my skills while a designer. On my education – I had the opportunity to engage on a Doctoral Programme in which the research subject was agreed between FEUP and CERN. Impact 19

WP1 WP2 WP3 WP4 WP5 COORDINATOR WORK PACKAGE LDR RESEARCHER ACEOLE MID TERM REVIEW CERN 3 RD AUGUST 2010 Blocks to be designed Calibration PLL mode - the auto calibration feature allows centring of the VCXO tuning range relating to the reference clock frequency. Oscillator mode - the auto calibration logic can be used to quickly choose the VCXO parameters that have to be programmed in the Fuse-Bank to tune the oscillation frequency. Frequency Offset Measurement Measures the offset between the central frequency and a reference Fuse Bank Fuses the default configuration of the PLL, after calibration. Uses a dynamic memory to operate in modes demanded by the user Control Interface Controls all the circuit operation and interfaces with the user with a 8-bit bus. AOAC The amount of power must be chosen in order to decrease phase-noise, and not to stimulate other crystal’s resonant modes, rather than the sheering of the crystal. Future Work 20
