What is Low Frequency Compensation? The coupling or blocking capacitor tilts the amplifier response for step input. In Fig. 16.28, if a high value of resistance Rd is added in…
Effect of Internal Transistor Capacitance: As we know already that at high frequencies, the coupling and bypass capacitors act as short circuit due to their low reactance and hence the…
Millers Theorem and its Equivalent Circuit: Millers theorem - Consider an arbitrary circuit shown in Fig. 15.13(a). As part of a larger network that is not shown, we have isolated…
Dual Gate MOSFET - N Channel Depletion Type MOSFET: Cross view of a dual-gate N-channel depletion type MOSFET is shown in Fig. 13.93. It acts as if two FETs are…
Enhancement Type MOSFET - Construction, Operation and Characteristics: Although DE-MOSFET is useful in special applications, it does not enjoy widespread use. However, it played an important role in history because…
Depletion Type MOSFET - Construction, Operation and Characteristics: As we know already that when the gate is biased negative w.r.t. the source in an N-channel JFET, the depletion-region widths are…
Metal Insulator Semiconductor Field Effect Transistors (MISFETs): The Metal Insulator Semiconductor Field Effect Transistors (MISFETs) is one of the most widely used electronic devices, particularly in digital circuits, because of…
FET as a Voltage Variable Resistor (VVR): FET is a device that is usually operated in the constant-current portion of its output characteristics. But if it is operated in the…
