Zusammenfassung:The design and evaluation of a high precision pulsed current source for the dynamic characterisation of shunts and burden resistors is described. This generator uses a set of current mirrors based on ratio resistor networks to amplify a 10 mA DC current reference and to subsequently generate a pulse by means of a complementary pulse approach. Simulations and preliminary results of the complementary pulse circuit will be presented.
