A very simple and cheap tv antenna amplifier circuit built with BF961 a N–Channel Dual Gate MOS common transistor used for input and mixer stages especially for FM- and VHF TV-tuners up to 300 MHz. L1 ...

This is a compact, easy to build amplifier that uses one IC only but delivers 40 watts of audio power. It is ideal for amplifying audio from your mobile CD player or iPod. The chip being used here is ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
