TEXT -416 -152 Left 2 ;Opamp gain depends on JFET resistance which is modulated by the modulating signal TEXT 64 -104 Left 2 ;Vsignal is the modulating 10kHz signal TEXT -408 184 Left 2 ;Modulated ...
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.
Discrete small-signal MOSFETs still find uses today, and this Design Idea presents two simple examples: an AND gate, and an amplitude modulator. Figure 1 shows a standard two-input AND gate along with ...
Abstract: We present a new multisectional model for high-speed electrooptic modulators, fully integrated within the framework of a microwave circuit computer-aided design (CAD) suite (MWOFFICE).
