[Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few feet. We’re suckers for some well-designed analog circuitry ...

Using this circuit you can realize a simple thermocouple amplifier which should give you enough gain to interface to your favorite controller providing it has an Analog to Digital Converter (ADC).

Noise analysis is very important in many analog and RF receiver circuit design since the received signals are very weak. In case of differential amplifiers the noise appear as common mode signal and ...

Because pulse modulation output signals are either on or off, Class D amplifiers produce far less heat than analog amplifiers. Reaching efficiencies greater than 90% compared to only 50% for ...

For example, a lot of audio equipment doesn’t have a dedicated headphone amplifier that’s tailored ... All the Mode adjustments are applied in the analog stage rather than digital, this ...
