VCO-Based Quantizers Using Frequency-to-Digital and Time-to-Digital Converters [Paperback]

This book introduces the concept of voltage-controlled-oscillator (VCO)-based analog-to-digital converters (ADCs). Detailed explanation is given of this promising new class of high resolution and low power ADCs, which use time quantization as opposed to traditional analog-based (i.e. voltage) ADCs.

Introduction.- VCO-Based Quantizer.- Limitations of the VCO Based Quantizer.- Further Analyses: FDC vs. TDC.- Conclusions.
Describes the use of Time-to-Digital Converters (TDC) in VCO-based quantizersUses VerilogA to model system non-idealities and develops behavioral models to capture the impact of both close-in and far-out phase noise of the VCO on both FDC and TDC based quantizersDevelops closed-form expressions to analyze the performance of the quantizers in the presence of non-idealitiesGB
