ABSTRACT:
A travelling wave sampler has an input terminal for receiving an input signal to be sampled. A first diode has its anode connected to the input terminal, whereas a second diode has its cathode connected to the input terminal. A first delay line is connected between the cathode of the first diode and the anode of a third diode, and a second delay line is connected between the anode of the second diode and the cathode of a fourth diode. A strobe generator provides negative-going strobe pulses to the cathode of the third diode through a first strobe capacitor and provides positive-going strobe pulses to the anode of the fourth diode through a second strobe capacitor. The third and fourth diodes are maintained in zero biased condition when strobe pulses are not provided by the strobe generator and are forward biased during the strobe pulses. At the end of a strobe pulse, the charge that was accumulated on the strobe capacitors during the strobe pulse drives the third and fourth diodes into reverse biased condition.
