A CMOS Blumlein generator including a two‐stacked‐metal–oxide semiconductor field effect transistor high‐voltage switch, a Blumlein pulse‐forming‐line (PFL) network and an on‐chip Klophenstein taper is presented. The Klophenstein taper is used to convert the high‐impedance load to 50 Ω. The Blumlein pulse generator is fabricated in a 0.13 µm CMOS process. Gaussian‐like pulses of 725 mV peak‐to‐peak amplitude, ∼126 ps duration and 3.18 GHz bandwidth are measured on a 50 Ω load (including the losses of the probes, cables and pads). After de‐embedding the connection system and Klophenstein taper, the pulses of 1.88 V and 114 ps duration are obtained, which are higher than the rated operating power supply of the given process.
