A 330 ps rise time, 19 dB gain and 3. 5 V maximal output voltage for a 25 OMEGA load amplifier is described. The frequency response was improved, reducing the Miller effect of the base to collector capacitance. For this purpose the first transistor of the series-shunt amplifier was replaced by a cascode configuration. High maximal output voltage was obtained by using a dc coupled, with a npn-pnp pair, circuit design.
