    Hello,

    I need some help concerning the design of simple CE amplifier.

    I am using the BC107B NPN transistor and in order to determine the frequency response of the amplifier, I need to know the junction capacitances of the transistor, i.e. C_{bc} , C_{be} and C_{ce}

    However the datasheets provide data only for C_{bc} and C_{be} .

    How do I get the value for C_{ce} ? Can I just calculate it as the capacitance obtained by the series connection of C_{bc} and C_{be} ?

    Thanks in advance
