| Abstract: | A method is suggested for cancelling the input capacitance of instruments and probes used in measurements. This approach is proposed as an alternative to conventional attenuating passive and active probes. The idea is demonstrated with a practical device that is able to nullify the parasitic capacitance to less than 2 pF without introducing signal attenuation |
