A graphene audio voltage amplifier is fabricated by overlapping the gate with source/drain contacts. The fabricated complementary amplifier has a voltage gain of 3.7 (11.4 dB) at 10 kHz, a total harmonic distortion in the audio frequency range of <1%, a unity‐gain frequency of 360 kHz, and a −3 dB bandwidth of 70 kHz.
