Abstract :
A fast DC coupled pulse amplifier with the following characteristics is described: rise time < 700 ps over an output range of +1 ... -3V with negligible ringing, voltage gain = 10, noise < 50 pV. Measured gain and phase response of a model amplifier are compared with calculations based on measured S-Parameters. Extended bandwidth and insensivity to stray reactances are achieved with a phase dependent feedback transfer function. Practical design guidelines are presented.
