  • Distortion compensation circuit
    Patent number: 5815038
    Abstract: A small-sized distortion compensation circuit is disclosed. In a semi-conductor element having three terminals, its gate is used as an input terminal. One of the drain and source is used as an output terminal, and the other is grounded. This structure does not need a conventionally used circuit comprising a complicated combination of distributors, couplers and attenuators, enabling the circuit to be smaller.
