Title:
SAMPLING CIRCUIT AND TESTER
Document Type and Number:
WIPO Patent Application WO/2006/051694
Kind Code:
A1
Abstract:
A circuit for sampling input signals comprising a pulser generating a pulse signal depending on timing at which the input signal is to be sampled, a step recovery diode outputting a sampling pulse depending on the pulse signal, a detector for detecting the value of the input signal depending on the sampling pulse, a circuit for detecting the temperature in the vicinity of the step recovery diode, and a temperature compensating section for controlling the sampling pulse outputting timing by the step recovery diode based on the temperature detected by the temperature detection circuit.
