A small 325mW amplifier with a voltage gain of 200 that can be used as a bench amplifier, signal tracer or used to amplify the output from personal radios, etc. The circuit is based on the National ...
OBJECTIVE: You will wind (and test) your own inductor, which you will also use in the AM radio project in a subsequent lab. You will also investigate the properties of capacitors by making a simple ...
The circuit in Figure 1a comprises a voltage follower, IC 1, and the reference-voltage source of IC 2. IC 1 is an Analog Devices AD8661 op amp, which has a guaranteed input-bias current of no more ...
If you enjoy building radio projects you may have noticed something slightly worrying over the last few years in your component supply. Variable capacitors are no longer as plentiful as they used to ...
