Due to its wider bandgap than silicon, a GaAs red light emitting diode (LED) typically has a turn-on voltage of 1.6 V. Assuming the maximum allowable current through the LED is 16.7 mA, what is the minimum allowable value of R (in Ohms) in the circuit below? Assume Vin = 4.8 V.
What is the maximum positive voltage at the output of the circuit? Assume Vin = 3.3 V AC (rms), R = [b] k Ohms, and Vd = 0.7 V.
What is the maximum negative voltage at the output of the circuit? Assume Vin = 2.3 V AC (rms), R = 2.6 k Ohms, and Vd = 0.7 V.
