Charge-Pump PLL with ring-oscillator based VCO in 65nm CMOS
In order to complete the transceiver which is part of a project aiming at correcting the motion in Magnetic Resonance Imaging, a Phase-Locked Loop (PLL) is needed to supply the clock to an Analog-to-Digital Converter (ADC). In order to have a better rejection of undesired signals, the reference clock available on the custom IC needs to be adapted to a higher frequency.
The first part of the project will consist in designing a ring-oscillator based Voltage-Controlled Oscillator (VCO) which is the milestone to realize a complete PLL. Afterwards, the design of several other blocks will have to supplement this VCO: Phase Frequency Detector (PFD), Charge Pump, Loop Filter and Divider.
The goal of this project is therefore to design a power efficient PLL with a low integrated jitter.
