Evaluation of Digital Crosstalk Noise to fully Differential VCO
نویسندگان
چکیده
Performance Index: We evaluate phase noise of VCO as a performance index of frequency domain, and cycleto-cycle jitter and cycle-jitter, as performance indices of time domain. The cycle-jitter is estimated from the histogram of period (Ti) in oscillation waveform, and, the cycle-to-cycle jitter is estimated by histograming the difference in periods from one cycle to the next (Ti-Ti-1). The cycle jitter is caused by low frequency component of noise and cycle-to-cycle jitter is caused by high frequency component. Each jitter was evaluated by the standard deviation (σ) and peak-to-peak (p-p) value.

Modeling and Simulation of Substrate Noise in Mixed-Signal Circuits Applied to a Special VCO
The mixed-signal circuits with both analog and digital blocks on a single chip have wide applications in communication and RF circuits. Integrating these two blocks can cause serious problems especially in applications requiring fast digital circuits and high performance analog blocks. Fast switching in digital blocks generates a noise which can be introduced to analog circuits by the common su...

PLLs are important building blocks that are used to generate and distribute clocks in all high-performance digital systems. Integrating PLLs on large digital chips in deep submicron processes poses three main challenges. First, power supply noise caused by increased digital switching currents degrades the jitter performance of the VCO. Second, the wide loop bandwidth required to suppress ring o...

This paper describes the design and optimization of voltage controlled oscillators with quadrature outputs. Systematic design of fully integrated LC-VCOs with a high inductance tank leads to a cross-coupled double core LC-VCO as the optimal solution in terms of power consumption. Futhermore, a novel fully differential frequency tuning concept is introduced to ease high integration. The concepts...

In this paper, we present a methodology to explore and evaluate the crosstalk noise and the profile of its variations, and the delay of interconnects through investigation of two groups of interconnect structures in nano scale VLSI circuits. The interconnect structures in the first group are considered to be partially coupled identical lines. In this case, by choosing proper values for differen...

A fully-digital VCO-based ADC featuring a novel beat frequency detection scheme is demonstrated in 65nm LP CMOS. The proposed beat frequency based ADC is unique compared to previous VCO-based ADCs in that it is highly effective in measuring extremely small changes (e.g., 0.01%) in the VCO frequency within a short sampling time (e.g., 100 VCO periods). Direct amplifier-less A-to-D conversion of ...
