CURRENT-TO-FREQUENCY CONVERTERS WITH FEEDBACK

Ján Hribik

   Two new current-to-frequency converter circuits for small input currents are given. Both circuits are based on the integration principle and contain feedback to the noninverting input of the integration amplifier. This feedback partially improves the dynamic properties and suppresses some undesired transients. Analysis of transients in the integrator during the discharge of the integrating capacitor is also given.

Keywords: current-to-frequency converter, integrator, transients analysis
