Abstract :
This paper pinpoints some design aspects on RC-oscillators for the synthesis of pure sine waveforms aimed at characterizing nonlinear distortion of high-resolution analog-to-digital converters. Preliminary results for a specific RC-oscillator indicate 2nd harmonic distortion 110 dB below carrier and much lower than this for higher order harmonics. Some ADC characterization results are shown.
