In this chapter a detailed analysis on the operation and architecture of the voltage-controlled oscillator (VCO)-based ADC is presented. The VCO-based quantizer is analyzed for two different architectures, one using a frequency-to-digital converter (FDC) the other a time-to-digital converter (TDC). Theoretical equations are derived to determine the resolution of these quantizers and verified through a VerilogA model.
