Delta‐doped Schottky diode nonlinear transmission lines for 480‐fs, 3.5‐V transients

Waveforms having 480‐fs, 3.5‐V transients were generated with a delta‐doped GaAs Schottky diode nonlinear transmission line and measured with an on‐chip diode sampling bridge at room temperature. Integration of delta‐doped diodes with high C(V) nonlinearity and uniform‐doped diodes with high speed made possible a transient waveform two times shorter than any previously measured.
