For a more analog MOSFET application, consider this simple AM modulator. Figure 4 MOSFET amplitude modulator The circuit consists of an N-channel MOSFET, two resistors, and a Schottky diode. The ...

In pulse position modulation, the amplitude and width of the pulses are kept constant, while the position of each pulse with reference to position of reference pulse, is changed according to the ...

• Providing an interferometric optical modulator which can be utilized as a digital photonic clock circuit, a pulse width/amplitude modulator circuit, and a bi-stable optical-memory cell circuit. • ...

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.

Here we report a flexible all-graphene modulator circuit with the capability of encoding a carrier signal with quaternary digital information.
