Application of diode in analog modulation circuit
Jing Zhang, Binbin Tao · 2022
Diodes have many functions, such as isolation, amplitude limiting, rectification, detection, voltage stabilization, constant current, variable capacity, switch, light emission, photoelectric conversion. This paper mainly studies the application of diode in analog modulation circuit, including linear modulation, such as amplitude modulation, demodulation, and nonlinear modulation, such as frequency modulation and phase modulation. Finally, the diode amplitude modulation circuit, diode envelope detection circuit and varactor frequency modulation circuit are simulated by multisim.
