    I have some questions about hfe parameter of bjt

    hi by temperture variation Bjt's parameter will vary. but how we can reduce these variation? hfe and Vbe are the parameters that vary with temperature. variation of Vbe will cause variation in Ib and variation in Ib and hfe will cause variayion in Ic. by biasing the bjt by a diode with same Vbe...
