Abstract/OtherAbstract:
|
The image shows an integrated graphene voltage amplifier, which paves the way for all-graphene analogue electronics. Signal amplification is obtained by fabricating graphene transistors in which the top gate overlaps with the source and drain contacts. This results in full-channel gating and therefore high transconductance at room temperature. 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. The obtained values demonstrate that, among other applications, the present graphene amplifier is suitable for high-fidelity amplification of audio signals. |
