ABSTRACT:
A sampling circuit for compensating the phase difference of a sampling pulse due to a temperature variation to accurately sample input signals is provided. The sampling circuit samples received input signals. The sampling circuit includes a pulse generator for generating a pulse signal according to a timing at which an input signal should be sampled, a step recovery diode for outputting a sampling pulse responsive to the pulse signal, a detector for detecting the value for the input signal according to the sampling pulse, a temperature detecting circuit for detecting the temperature around the step recovery diode and a temperature compensating unit for controlling a timing at which the step recovery diode outputs the sampling pulse based on the temperature detected by the temperature detecting circuit.
