Many applications require a circuit to perform pulse modulation and voltage amplification to drive a load with a train of impulses. A typical application is driving a piezoelectric generator in a ...

Remarkably, both modulation schemes can be realized with just 1 and 2 all-graphene transistors, respectively, representing a drastic reduction in circuit complexity when compared with conventional ...

Here, we demonstrate experimental proof of principle for the operation of excitonic switching devices at temperatures around 100 K. The devices are based on an AlAs/GaAs coupled quantum well structure ...

This circuit includes matched quad DMOS transistors for the upper differential pairs, U1A, U1D, and U1B, U1C. A second set of matched DMOS transistors form another differential pair on the both with ...

This paper presents new chopper modulators which can able assign three modulators in one circuit. It consists of Cowan, Ring and amplitude modulators. The proposed circuit is implemented from the ...

Curious how a solar-powered lamp powers an LED with just a single 1.2-V cell? In a 2012 edition, Elektor presented a clever single-transistor voltage converter circuit by Burkhard Kainka.Let's ...

The team introduced a conductive polymer into the vascular system of plants, which allowed the researchers to create the key components of an electrical circuit. They were also able to demonstrate ...
