Out of the loop compensation technique uses a simple resistor to isolate the capacitive load with the op-amp, lowering the capacitive loading of the op-amp. The resistor typically varies from 10-50 Ohms but the increase in isolated resistor effects the op-amp bandwidth.

Discharge resistors are also used for each capacitor to discharge it after being disconnected from the supply in a relatively short time interval. To calculate the maximum discharge resistance, a ratio between the maximum discharge time approved by IEC60831 and a logarithmic capacitor charging must be applied.
