This paper describes a simple, analytical expression for quantization noise in a time-to-digital converter (TDC) based on Fourier-series analysis. We analyzed inverter propagation-delay variations due to fluctuations in the threshold voltage, and here we also discuss phase noise in an all-digital phase locked loop (ADPLL). The large standard deviation in the threshold voltage degrades phase noise even under short inverter-delay conditions. Increasing the gate area of transistors led to low phase noise due to threshold variations, but greatly increased power consumption. The paper also discusses TDC power reduction method without degrading quantization noise. Our analytically predicted results agreed well with the data obtained from a Spectre-RF simulator.
