Photodiode Figure 3-31. – Photodiode. A second optoelectronic device that conducts current when exposed to light is the PHOTOTRANSISTOR. A phototransistor, however, is much more sensitive to light and produces more output current for a given light intensity that does a photodiode. Figure 3-32 shows one type of phototransistor, which is made by placing a […]

Jfet symbols and bias voltages , effects of bias on n-channel depletion mosfet , summary of special devices and answers to questions q1. Through q44.
JFET symbols and bias voltages Figure 3-50. – JFET symbols and bias voltages. Because the materials used to make the bar and the gate are reversed, source voltage potentials must also be reversed. The P-channel JFET therefore requires a positive gate voltage to be reverse biased, and current flows through it from drain to source. […]
