ABSTRACT:
In order to avoid signal reflections, a transmission line connected to an electronic circuit is terminated by a terminating impedance. The value of the terminating impedance is to match in the best possible way in the frequency zone of the circuit with the value of a characteristic impedance of the transmission line to be terminated. The invention provides an electronic circuit in which the terminating impedance is a series combination of an active impedance and a passive impedance. The passive impedance is of the same order of magnitude as the characteristic impedance. The terminating impedance matches well with the characteristic impedance of the transmission line even at high frequencies. By modifying the settings of the active impedance, both the value of the terminating impedance and the DC voltage on a transmission line termination can be set.
