However, a sample circuit diagram and some waveform pictures are shown in Figs. 5–8. For this project, studying the following topics was helpful: 1. Principles of AM modulation. Understanding the ...

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 ...

To understand this circuit, we can split it into two AM modulators. The first AM modulator includes U2A with U1A and U1D. The second AM modulator has U2D with U1B and U1C. In a common configuration as ...

Signal modulation is a mechanism which embeds an information-carrying signal into a carrier wave to broadcast information and is essential for high-speed communication. Zhonget al. report a ...

• 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.
