the emitter area sizes are as follows the fourth preferred embodiment assigns the ratio of the 2 branches based on the ratio 1 2 referring to fig3 again for the fourth embodiment the relationship between the emitter area sizes are as follows as mentioned in the beginning of this section there is an rlc circuit contributing to the u201c ringing u201d by reducing the inductive nature of zout the variation seen at the output signal will be at a high frequency but at smaller magnitude from fig4 c the inductive nature of the output impedance can be related to its parasitic capacitance by l c u03c0 r u03c0 r s u03b2 o by splitting the transistor into several branches the parasitic capacitance c u03c0 can be reduced hence decreasing the inductive nature also by having the 2 branches to have different sizing the rlc circuit would experience different settling time and magnitude this will further average out the variation at the output signal in the fourth preferred embodiment a ratio of 1 2 is used for a 2 branched system this ratio is chosen as it would ensure the difference in the inductive nature between the two branches to be about twice allowing a smoother averaging effect to between the two branches fig6 a and 6b show the fifth preferred embodiment according to the present invention multiple unit transistors are arranged in parallel to obtain an equivalent emitter area of the initial transistor hence as an example based on the third preferred embodiment to construct q 1 a multiple q 1 a.
