TYPICAL CONNECTION CIRCUIT
Transition time and overshoot adjustment is made possible using the circuit of Figure 1. LA peaks the amplifiers
frequency response at the cathode yielding optimum rise and fall times. A good starting point value for this inductor
is 0.1µH. The tradeoff that must be dealt with when peaking an amplifiers' response is increased overshoot. Once
the rise and fall times have been adjusted with LA, the overshoot can be damped by adjusting CA, RD1 and RD2 in
Figure 1. Keep in mind that as the value of load capacitance increases, so will the overshoot. Starting with 499Ω
resistors for RD1 and RD2 and 150pF for CA, the overshoot can be minimized by adjusting RD1 and RD2 up or down.
