This thesis covers the analysis, design and simulation of a low-power low-noise CMOS Phase-Locked Loop (PLL). Starting with the PLL basics, this thesis discussed the PLL loop dynamics and behavioral modeling. In this thesis, the detailed design and implementation of individual building blocks of the low-power low-noise PLL have been presented. In order to improve the PLL performance, several novel architectural solutions has been proposed. To reduce the effect of blind-zone and extend the detection range of Phase Frequency Detector (PFD), we proposed the Delayed-Input-Edge PFD (DIE-PFD) and the Delayed-Input-Pulse PFD (DIP-PFD) with improved performance. We also proposed a NMOS-switch high-swing cascode charge pump that significantly reduces the output current mismatches. Voltage Controlled Oscillator (VCO) consumes the most power and dominates the noise in the PLL. A differential ring VCO with 550MHz to 950MHz tuning range has been designed, with the power consumption of the VCO is 2.5mW and the phase noise -105.2dBc/Hz at 1MHz frequency offset. Finally, the entire PLL system has been simulated to observe the overall performance. With input reference clock frequency equal 50MHz, the PLL is able to produce an 800MHz output frequency with locking time 400ns. The power consumption of the PLL system is 2.6mW and the phase noise at 1MHz frequency offset is -119dBc/Hz. The designs are implemented using IBM 0.13µm CMOS technology.

This thesis describes the design and implementation of a fully monolithic 10 Gb/s phase and frequency-locked loop based clock and data recovery (PFLL-CDR) integrated circuit, as well as the Verilog-A modeling of an asynchronous serial link based chip to chip communication system incorporating the proposed concept. The proposed design was implemented and fabricated using the 130 nm CMOS technology offered by UMC (United Microelectronics Corporation). Different PLL-based CDR circuits topologies were investigated in terms of architecture and speed. Based on the investigation, we proposed a new concept of quarter-rate (i.e. the clocking speed in the circuit is 2.5 GHz for 10 Gb/s data rate) and dual-loop topology which consists of phase-locked and frequency-locked loop. The frequency-locked loop (FLL) operates independently from the phase-locked loop (PLL), and has a highly-desired feature that once the proper frequency has been acquired, the FLL is automatically disabled and the PLL will take over to adjust the clock edges approximately in the middle of the incoming data bits for proper sampling. Another important feature of the proposed quarter-rate concept is the inherent 1-to-4 demultiplexing of the input serial data stream. A new quarter-rate phase detector based on the non-linear early-late phase detector concept has been used to achieve the multi-Giga bit/s speed and to eliminate the need of the front-end data pre-processing (edge detecting) units usually associated with the conventional CDR circuits. An eight-stage differential ring oscillator running at 2.5 GHz frequency center was used for the voltage-controlled oscillator (VCO) to generate low-jitter multi-phase clock signals. The transistor level simulation results demonstrated excellent performances in term of locking speed and power consumption. In order to verify the accuracy of the proposed quarter-rate concept, a clockless asynchronous serial link incorporating the proposed concept and communicating two chips at 10 Gb/s has been modelled at gate level using the Verilog-A language and time-domain simulated.
Abstract :- Serial links behave as arteries of computing systems while transferring data from one point to the other and clock and data recovery (CDR) block has the responsibility of recovering the bits error-free at the other end of transmission. This tutorial will present the basic requirements of CDRs and relate their performance metrics to different architectures and loop components with tradeoffs for different implementations. Particularly, this tutorial will compare different CDR architectures: linear vs. bang-bang, full-rate vs. sub-rate architectures, analog vs. digital vs. hybrid loops, oscillator vs. phase interpolator vs. embedded phase-locked loops (PLLs), reference-less vs. reference-based CDRs, and CMOS vs. CML vs. charge-based receiver front-end of CDRs.

Prof. McNeill's Ph.D. thesis [1, 2] investigated sources of noise in an integrated voltage controlledoscillator (VCO) used in a clock recovery phase-locked loop (PLL). A simple design technique wasdeveloped to establish correspondence among time and frequency domain measures of jitter with thePLL loop open or closed. Then the fundamental sources of jitter in a bipolar differential pair delaystage were identified, leading to a design procedure which gives explicit constraints on circuit elementsas a function of desired system-level jitter performance. This technique has been verified accurate towithin 10% in predicting system-level, closed-loop jitter over a 155MHz to 622MHz frequency rangein the XFCB and XF1.5 dielectrically isolated complementary bipolar processes. There is considerableinterest in extending these results into the corresponding CMOS circuitry for applications such asclock multiplication in digital modulator ICs. The research proposed for this fellowship would involvefabrication of ring VCO and basic PLL structures in single poly, 0.6�m 5V/3V and/or 0.35�m 3Vprocesses. Possible test structures include:
