an amplifier circuit includes a first multiple gate field - effect transistor having a source terminal , a drain terminal , at least one signal gate terminal for receiving an input signal and at least one control gate terminal for receiving a control signal , and a second multiple gate field - effect transistor having a source terminal , a drain terminal , at least one signal gate terminal connected to the signal gate terminal of the first multiple gate field - effect transistor , and a control gate terminal connected to the control gate terminal of the first multiple gate field - effect transistor , the signal gate terminal of the second multiple gate field - effect transistor being connected to that source terminal / drain terminal of the second multiple gate field - effect transistor which is closer to the signal gate terminal of the second multiple gate field - effect transistor .
