This circuit combines a modulator and an amplifier into a single stage. The compactness of the circuit makes it appropriate for portable-system applications. The load is in series with two switches ...

If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Applications for an Inferometer Modulator The present technology relates generally to computer optical processing circuits using interferometric techniques, and more specifically, to an interferometer ...

The notion of a phased array was initially articulated by Nobel Prize recipient K. F. Braun. Phased arrays have subsequently ...

Zhonget al. report a flexible, transparent all-graphene modulator circuit performing quaternary modulation schemes with only two transistors.

The upshot of this opera tion for use as a pulse-width-modulator circuit is an approximate triangle wave (Fig. 2). The triangle wave is employed as the input to op-amp U2.
