This bridge permits measuring the capacitances of voltage-dependent capacitors, such as MOS capacitors, by means of a pulsed bias source. As there is a low resistance output circuit, the pulsed source causes no ringing of the output transformer of the bridge. The bridge can be used to measure the various interesting characteristics of a MOS structure, such as doping profile, flatband voltage, etc.
