Matt circuit

You're already familiar with Proteus and its usage. It's really interesting to simulate your circuit before hardware implementation because it's just a matter of few clicks here and there before you can see the output. Sometimes there are too many connections in your circuit which kind of looks ugly. This article is about using BUS WIRE in Proteus which saves you some space in the design area and the circuit also looks presentable rather than a mess of connections. READ MORE

This portable AM and FM radio circuit is designed using the LA1800 IC and some other external components. As you can see in this circuit diagram the LA1800 manufactured by Sanyo Semiconductors , require few additional components. The LA1800 am FM portable radio circuit needs to be powered from a 3 volt DC power supply circuit. You can use an 3 volt battery. This radio receiver circuit has a low current dissipation of 5.6mA for FM band and 3.2mA for AM band .Also the output signal is driven into earphone speakers , but you can use an additional speaker ( in that case you need to connect an additional small power audio amplifier).
