However, if we incorrectly design our amplifier circuit and set the biasing Q-point at the wrong position on the load line or apply too large an input signal to the amplifier, the resultant output signal may not be an exact reproduction of the original input signal waveform. The Power, Voltage or Current Gain, (amplification) provided by the amplifier is the ratio of the peak output value to its peak input value (Output ÷ Input). The bias Q-point setting will give us a “Class-A” type amplification configuration with the most common arrangement being the “Common Emitter” for Bipolar transistors or the “Common Source” configuration for unipolar FET transistors. A DC bias is required so that the amplifier can amplify the input signal over its entire cycle with the bias “Q-point” set as near to the middle of the load line as possible. Also used in electronics such as interactive toys, Robots & Hi-Fi devices.For a signal amplifier to operate correctly without any amplifier distortion of the output signal, it requires some form of DC Bias on its Base or Gate terminal.Also used in the military for advanced warfare applications such as acoustic weapons.An important part of the home entertainment audio systems.

Mainly used in the music industry such as audio frequency amplifiers & headphones.The 10nF electrolytic capacitor likewise blocks the DC voltages of this particular biasing of transistor Q2 & delivers the audio output on devices such as headphones. Also, it offers additional amplification. Transistor Q2 acts as a fixed bias by using a 100kΩ resistor.

The 10μF capacitor eliminates DC voltages due to the biasing of Q1. The output of Q1 reaches the collector of Q2, serving as an input. This resistor offers negative feedback for the transistor Q1. Transistor Q1 is set up as a collector to base biasing function, by connecting a 180KΩ resistance.

A 10μF capacitor is attached to the input to block DC components of the transmissions, Allowing AC components of the input to pass through.Ī 4.7KΩ resistor offers the necessary biasing to the condenser microphone. Audio input is provided via an audio transducer such as a Condenser microphone, which will turn the audio signal directly into an electrical signal.
