Abstract
A digital four-arm bridge for the comparison of resistance with capacitance has been designed and demonstrated. The digital bridge mimics the classical quad bridge in the digital domain with three balances: the source balance, the detector balance, as well as the main balance. Due to correlation, the required precision of the source voltages is only of the order of the square root of the ultimate bridge precision. For the comparison of a 100 kΩ resistor with a 1 nF capacitor near 1592 Hz the combined standard uncertainty (k = 1) is 5 × 10^−9.Citation
