  1. 1. Temperature Compensation in CMOS Ring Oscillator

    Master-uppsats, Linköpings universitet/Elektroniska Kretsar och System

    Författare :Xiaohua Wei; Dingyufei Zhang; [2022]
    Nyckelord :Current Starved Ring Oscillator CSRO ; Temperature compensation; Supply voltage compensation; Stable frequency; Digital controlling; Phase Frequency Detector PFD ; Dynamic comparator; Bidirectional counter; Charge pump CP ; Frequency divider; Power consumption; AMS 0.35 um; EDA tool Cadence;

    Sammanfattning : A digital system is often required to operate under a specific frequency. A ring oscillator can be helpful in this circumstance because it can generate a signal with a specific frequency. However, a ring oscillator is also sensitive to the environment temperature. LÄS MER
