-In the current mirror configuration,​ the op amp serves as a virtual ground at the mirror input (base) node to convert the voltage steps from AWG 2 ( W2 output ) into current steps through the 1KΩ resistor. The collector voltage is swept using a ramp from AWG 1(output W1). Load the stairstep.csv file, set amplitude to 1.5  (3V peak to peakwith the offset to 1.5V. +In the current mirror configuration,​ the op amp serves as a virtual ground at the mirror input (base) node to convert the voltage steps from AWG 2 ( W2 output ) into current steps through the 1KΩ resistor.

 If you don't want to use the op-amp configuration the following simplified configuration can be used as well. If you don't want to use the op-amp configuration the following simplified configuration can be used as well.
