10x Linear Laboratory Amplifier


The aim of this project was to develop a linear analogue amplifier designed for laboratory use. This amplifier has to realise a voltage amplification of 10x and is intended to amplify function generator signals for tests.

  5. Tests
    During the tests, no problems have occurred. The amplifier ran several days with a high voltage output signal (±40V square wave with 20kHz) without any variation of the signal.
