Ultrafast photoconductive (PC) sampling techniques have been used in the measurement of electrical waveforms with picosecond resolution and high sensitivity. In this work, an integrated JFET source follower/amplifier, with its high input impedance and low input capacitance (3 pF), has been found to sense absolute signal voltages noninvasively, with as much as 150 times larger output signal levels than those of unamplified PC gates.
