This EXMATEC 2010 paper by Handel, Truong, and Nasiri Avanaki examines fundamental 1/f piezoelectric transducer size fluctuations. The research analyzes how quantum 1/f noise manifests as random fluctuations in the physical dimensions and resonant frequency of piezoelectric transducers and resonators, showing that these fundamental size fluctuations establish lower bounds on frequency stability in quartz oscillators, MEMS resonators, and acoustic sensors, with implications for timing applications and precision frequency control.
