TRANSISTOR CIRCUITS FOR ANALOG AND DIGITAL SYSTEMS 307 resulting current transmission. The amplitude of the transmission fallsoff at a rate of 6 db per octave with the corner frequency C05 determinedby C3 and the low frequency value of the transistor input inductance L3 introduces a 12 db per octave rising asymptote witha corner frequency at C03 = WLsCs . The corner frequencies C03 and C05are selected in order to obtai
