| Abstract: | A design of the charge-amplifier has been developed,some new ideas have been advanced for reducing the influence of the maxi- mum output current and the rate of rise (S R)of the operational amplifier upon the highfrequency response of the charge amplifier. They are proved theoretically and verified experimetally.On this basis,a single-source charge-amplifer for static calibration of piezoelectric transducers has been construeted,which can be versa- tilely used in various test systems using piezo-eleetrie sensors. |
