IMPROVING THE LINEARITY OF AN ANALOG VOLTAGE-TO-PERIOD CONVERTER

Mojmír Kollár

   One type of a simple analog voltage-to-period converter is modified and its features are analyzed with aim to improve the linearity of its characteristic namely in upper part of working-frequency range. It is shown that reinforced current injection by overcompensating the feedback divider improves its performance. Analytical solution of the circuit allows effective simulation in order to optimize the converter characteristic.

Keywords: voltage-to-frequency converter, overcompensated divider, linearization, circuit analysis
