摘要：

An analytical study about the input offsetvoltage and current in varicap diode modulators is presented. Some relations for defining their value and their temperature drift are established. Diode selection to minimize the offsetvoltage and current is considered. Analytical results are proven in an electronic electrometer with a modulator using reverse polarized diodes. With this electrometer a 31 μV/°C input offsetvoltage, a 0.1-pA input offset current and a 0.016 pA/°C temperature drift are obtained.
