Evaluation of characteristics of an HV electrometric amplifier with low input current
Original language description
In certain special applications, for example in various fields of chemistry, it is necessary to measure voltage in the order of hundreds of volts from a high-impedance source. Standard electrometric operational amplifiers cannot be used as their input range is limited to the maximum of ten volts. Furthermore, it is impossible to increase the input range by a voltage divider in situations when the required input resistance is, for example, 10^14 Ohm. A common resistive divider in the input of an operational amplifier typically shows the maximum input resistance of 10^12 Ohm. A special circuit arrangement can be used in which the amplifier supply voltage is dynamically shifted with the input voltage. This configuration saves the high input resistance ofthe applied electrometric amplifier and extends the input voltage range to the desired value. In our configuration, the extended range is +-300 V. The proposed design of an HV electrometric amplifier utilizes a high-voltage differential a
