Audio inverting amplifier

The views of Vladimir Katkov about the configuration of audio inverting amplifier, are discussed. The amplifier features an open-loop gain of more than 3000 in the whole audio 20Hz-20kHz. VK-1,2 instruments acquire data that shows the reliability of the amplifier. The simulation of the circuit have been performed with the help of Multisim 9 software, which also confirms the reliability. He states that the temperature stability of the currents and voltages of the amplifier depends on the emitter-base potential of the involved transistors of diodes. Additional resistors can be used to make the circuit work as a linear amplifier with a fixed gain. The amplifier is also simulated by the software, which offers a powerful set of tools and virtual instruments for all conceivable types of circuit analysis.
