Abstract :
A quadrature bridge has been developed with the aim of determining capacitance values at several frequencies in terms of a resistance ultimately derived from the QHR. The bridge is evaluated by comparing a 1 nF capacitor with a 100 k/spl Omega/ resistor at six frequencies from 3/8/spl times/10/2/spl pi/ kHz to 10/2/spl pi/ kHz.
