The objective of this lab was to design a practical audio microphone amplifier. At the same time the DC imperfections of the LM741 Op-Amp were investigated and strategies to minimize the overall DC ...

This is a low cost design, of a amplifier with a electret microphone capsule for the ADC of a 3.3V micro-controller. Using the OpAmp LM358P with 3 stages. 1º JFET stage, 2º and 3º OpAmp stages. The ...

We’re talking of course about the carbon microphone amplifier, a piece of telephone technology which made its way into consumer electronics. The carbon microphone is a container of loosely ...

I've got a high impedance (3-10pF), low noise(<140dBV at 1Khz) microphone that I would like to pair with a high gain amp. Looking through the TI-Burr Brown pages I ...
