Many PWM (pulse-width-modulated) applications, such as Class D audio amplifiers, require symmetric drive circuitry. Comprising complementary N- and P-channel FET devices with gates and sources ...
Determine VGS and VDS for the E-MOSFET circuit in the figure. Assume this particular MOSFET has minimum values of ID(on) = 200mA at VGS = 4V and VGS(th) = 2V. We then calculate ID for VGS = 3.13V.
Despite recent improvements in the performance of RF LDMOS field-effect transistors (FETs), temperature drift and aging continue to affect the efficiency and linearization of power amplifiers using ...
An N-channel JFET has a low bias current when its gate is biased negative to the source. However, this requires either that the gate voltage be biased negative with respect to the source voltage or ...
