SNDR Limits of Oscillator-Based Sensor Readout Circuits

SNDR Limits of Oscillator-Based Sensor Readout Circuits

This paper analyzes the influence of phase noise and distortion on the performance of oscillator-based sensor data acquisition systems. Circuit noise inherent to the oscillator circuit manifests as phase noise and limits the SNR. Moreover, oscillator nonlinearity generates distortion for large input...
