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.

This paper present a virtual instrumentation system for learning the Operational Amplifiers (Op Amps) circuits function, design and analysis. By combining the schematic diagram and simulation tools ...

Components Required to Build TDA7294 Based Amplifier Circuit This circuit is very easy to replicate because we used generic components to build it, you can find the pars requirements for this project ...

In the simple circuit shown in Figure 9.9 (the case shown is for an NPN transistor, but a virtually identical circuit, but with negative supply rails, could be made with a similar PNP transistor), the ...

Circuit Connection – Step 1 To make this Mini Power Amplifier Circuit, 1st we connect 10 KΩ resistor with “Drain” and “Gate” leg of mosfet. Then we connect 47µf/16v capacitor with the circuit. We ...

A novel design technique for closed-loop amplifier circuits, suited to very low supply voltages, is proposed. It is based on the use of quasi-floating gate MOS transistors, thus avoiding issues ...
