Crystal negative resistance

WebNext, the negative resistance of this circuit is to be explained further. In equation (2), if you substitute for C02, the negative resistance -R will be -. The negative resistance will reduce in inverse proportion to the square of the frequency. Therefore, C01 and C02 must be of sufficiently small values WebThe negative resistance, Re {Z APPLIED }, has the following characteristics: Is always negative. The absolute value of the negative resistance drops as C SHUNT increases. …
