Abstract
This work demonstrates a self-referenced CMOS LCO, or CMOS harmonic oscillator (CHO), that exhibits 90ppm total frequency error over process, bias and temperature, thus making it suitable for replacing XOs in many applications. Additionally, the clock generator can be configured to produce a number of different output frequencies, has 1/4 of the frequency error of the oscillator in [3] and includes a direct modulation technique enabling SSCG.
