    摘要: This disclosure describes techniques and methodologies of using passive continuous time (CT) delay line for high-speed CT analog-to-digital converter (ADC) applications. In a continuous-time residual producing stage common to these CT ADCs, a proper delay between the analog input and DAC output is crucial. Specifically, using an inductor-capacitor (LC) lattice based delay element to enable high-performance CT pipeline ADC and CT delta-sigma (ΔΣ) ADC. The use of an LC lattice based delay element provides wide-band group delay for continuous-time signals with well-controlled impedance. This will be an essential circuit component to build a high-performance CT ADCs especially in architectures where the generation of a low-noise and low-distortion residual between the CT signal and its digitized version is needed. LC lattice based delay element enables noise-free, distortion-free wideband delay that is required for high speed continuous-time pipeline ADC and delta-sigma ADC.
