Abstract :
The paper describes some load compensation circuits for a wide-band transformer employed in precise measurements of ac voltages in the millivolt ranges, for frequencies up to 1 MHz. By means of these circuits the load sensitivity of the transformer is reduced, so allowing the generation of precise ac voltages.
