SC無安定マルチバイブレータによるm/n分周器

抄録

The m/n frequency divider founded on the new multivibrator using the switched-capacitor (SC) circuit and the CMOS logic gate is described. In this multivibrator, the electric charge is transmitted between the capacitor of the SC circuit and the coupling capacitor of the multivibrator by the input signal. And with the gate voltage up and down in the staircase, the circuit state is inverted momentarily. By means of the logical product of the multivibrator output, an m/n frequency divider is obtained. (m and n are any positive integer and set on m<n) This divider has a wide synchronization range and a steady operation. And divided frequency ratio is conveniently changed with varying the coupling capacitor of the multivibrator. The calculated values are in agreement with the measured values.
