  • Abstract
    Reports on the improvement of frequency responses of a logarithmic amplifier with a Paterson transdiode connection. The improvement of the response speed has been achieved by using a phase compensation technique. Small- signal response analysis of the logging circuit revealed the effects of a series resistor RP and a parallel capacitor CP on the response of the circuit. The improvement of the frequency characteristics is remarkable at high current levels. These facts were proved by the practical logarithmic amplifier.
