Abstract :
A novel precision arc resistance divider made of thin-film resistors is described. Its advantages are accurate ratios, very low output impedance (0.001 Ω), small size, and light weight. The ratio and angle errors of all required ratios are not greater than 200 p.p.m. and 200 mrad for 40 Hz-10 kHz. The maximum allowable input voltage is 600-V RMS
