Low-distortion cascode circuit

摘要

An electronic circuit is provided with a first field effect transistor and a second field effect transistor, in which a drain of the first field effect transistor connected to a source of the second field effect transistor. This electronic circuit inputs a first signal to a gate electrode of the first field effect transistor, inputs a second signal to a gate electrode of the second field effect transistor and outputs a signal from a drain of the second field effect transistor. This electronic circuit is a cascode circuit related to the current drivability of the second field effect transistor is set to be larger than the current drivability of the first field effect transistor, and there is an effect that third-order or higher order distortion characteristics of a cascode type or dual-gate circuit can be reduced.
