MOSFET AUDIO AMPLIFIER(Low Noise and High Gain) : 6 …
https://www.instructables.com/MOSFET-AUDIO-AMPLIFIERLow-Noise-and-High-Gain/
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 …

Zeus Stereo Mosfet Preamplifier Prototype. The prototype front panel layout is going to be reorganised with the volume control in the centre and the input selector to one side. A hard mute/standby switch will be on the other side to balance the visual appearance. Notes: Each channel has it's own voltage regulator (I used LM317HVs set

3. 50 Watts Mosfet Amplifier Description: The first stage of the amplifier is a differential amplifier based on transistors Q1 and Q2. Capacitor C8 is the input DC decoupler, R1 limits input current and capacitor C1 bypasses unwanted high frequencies. The second stage is the driver stage consisting of transistors Q3 and Q4.

Field Effect Transistor is an amplifying device in which the output current depends on the input voltage. The FET Pre Amplifier described here is a sensitive and stable Preamp circuit using an N-Channel FET and a PNP Bipolar transistor. This combination gives high input impedance and low output impedance with stabilized gain. The Junction FET

HotFET Pre: J-FET audio preamplifier schematics ... However, applying the same principles while using depletion MOSFET’s cascoding J-FET’s – I’ve successfully built a differential amplifier with controlled gain (no loop NFB). It performs beautifully! People even say it exhibits somewhat “tube-ish” character 🙂
