VCO-Based quantizers using frequency-to-digital and time-to-digital converters

This book introduces the concept of voltage-controlled-oscillator (VCO)-basedanalog-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. Describes the use of Time-to-Digital Converters (TDC) in VCO-based quantizers Uses 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 onboth FDC and TDC based quantizers Develops closed-form expressions to analyzethe performance of the quantizers in the presence of non-idealities INDICE: Introduction. VCO-Based Quantizers. Limitations of the VCO Based Quantizer. VCO-based Quantizer in DS Modulator. Conclusions and Future Work.
