Abstract
The invention relates to instrumentation equipment and can be used for controlling parameters of semiconductor devices. A capacitance measuring device comprises a high-frequency generator, controlled amplifiers, blocking capacitor, resistor of ohmic capacitive divider, switch, amplifier, detector, digital-to-analog converter, comparator units, divider, terminals for connection of reference voltage, pulse counters, mode setting unit, two-input coincidence units, pulse generator, pulse formers, flip-flops, decoupling element. The technical result is in exclusion of output signal dependence on parameters of high-frequency circuit, i.e. amplifier and generator, as main sources of instability.
