Interface circuit for frequency converter output has current path coupling signal input to signal output with cascode stage, second path with parallel cascode stage, common mode port

摘要

The interface circuit has a signal input, a signal output, a first current path (10) that couples the signal input to the signal output and contains at least one cascode stage (12,13), a second current path (20) with a cascode stage (22,23) connected in parallel to the first cascode stage and a connection for providing a common mode signal (28) in the first or second current path.
