Let's crunch some numbers. Assume our power MOSFET has K=2.0A/V2 and VT=2.0. Also, assume we are driving a RS=16Ω earphone load. If we bias the input so that VIN=6.4V, what is the bias voltage VOUT (in Volts) across the earphone?

    If you get this right, rest is just math, 1-1/sqrt(1+2K*RS*(VIN-VT))

    My dear friend, plug in values here - vin*(1-1/sqrt(1+2K*RS*(VIN-VT))))
