of the audio power amplifier is set as low as possible. If the audio power amplifier’s gain is set too high, then it amplifies the noise floor, along with the actual wanted signal of the CODEC or DAC. This decreases the dynamic range of the signal and reduces the quality of the sound.
MOSFET AUDIO AMPLIFIER(Low Noise and High Gain) : 6 …

It simply amplifies the input signal and produces gain according to the equation (1). Gain = [ ( R1 || R2)/ (rs+ R1 || R2 ) ] * (-gm) * ( rd || RD || RL) (1) Here, R1 and R2 are the input resistances, rs is the source resistance, RD is the resistance between bias …

Every 6dB of gain equates to a doubling of voltage; as such, a hypothetical amplifier with a voltage gain of 30dB will increase voltage by 2^5, or by a factor of 32. For unbalanced inputs, the THX standard gain level is 29dB; utilizing balanced inputs decreases this to 23dB, though naturally the output of the preamp is boosted by 6dB under this scenario (i.e. …
