Question

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=6.1V, what is the bias voltage VOUT (in Volts) across the earphone?

Answer 1

Vout=(Vin-VT-Vout)^2*RL

Answer 2

Solve for the resulting quadratic, taking the appropriate root, you'll get the answer.

Answer 3

Thank you it worked :D I was missing so many () it wasnt even funny
