The active terminal circuit and the distributed amplifier null which uses

摘要

PROBLEM TO BE SOLVED: To provide an active terminating circuit suitable for widening the band of a distributed amplifier. SOLUTION: This circuit is composed of a source-grounded transistor 2, gate-grounded transistor 3 cascade connecting a source terminal to the drain terminal of the transistor 2, resistor 4 connected between the gate terminal of the transistor 2 and the drain terminal of the transistor 3, and resistor element 5 connected between the drain terminal of the transistor 3 and a power source terminal 6.
