This paper proposes the estimation method of the threshold voltage (Vth) of the transistor from the frequency of the ring oscillator (RO) without analog measurement. Two distributions of delays, in which the contour lines are nearly orthogonal with each other, are derived from the measured frequencies of three kinds of ROs. The Vth can easily be calculated from the two distributions by fitting to...
The present study aimed to quantify the thickness of articular cartilage (Tc) in vitro using both conventional and real-time spatial compound B-mode ultrasonography (US) with a clinically used transducer and to evaluate the accuracy of measurement by comparing the results with values obtained microscopically. Femoral condyle samples were obtained from a 6-month-old pig and a 3-year-old pig. B-mode...
