Parametric Amplifier Types: The basic Parametric Amplifier Types have already been discussed in detail, but several others also exist. They differ from one another in the variable reactance used, the bandwidth required and the output…
Parametric Amplifier: The parametric amplifier uses a device whose reactance is varied in such a manner that amplification results. It is low-noise because no resistance need be involved in the amplifying process. A varactor diode…
Parameters of Operational Amplifier: Two Important Parameters of Operational Amplifier are the slew rate and the power supply rejection ratio (PSRR). Let us discuss and obtain the expressions for these two Parameters of Operational Amplifier…
Parameters of JFET: JFET has certain parameters which determine the performance. Such Parameters of JFET are (i) ac drain resistance, (ii) transconductance, (iii) amplification factor, and (iv) dc drain resistance, as explained below: 1. AC…
Parameter Passing Techniques in Microprocessor: Parameter Passing Techniques in Microprocessor - Whenever we need to use a group of instructions several times throughout a program there are two ways we can avoid having to write…
Paralleling Field Coils for DC Series Motor: In this Paralleling Field Coils method, used in fan motors, several speeds can be obtained by regrouping of field coils, as illustrated in Fig. 1.72 (c). In case…
Parallel RLC Circuit Resonance: Parallel RLC Circuit Resonance - Basically, parallel resonance occurs when XCÂ = XL. The frequency at which resonance occurs is called the resonant frequency. When XC = XL, the two branch currents…
Parallel Plate Capacitor in IC Fabrication: The Parallel Plate Capacitor in IC Fabrication structures are as shown in the Fig. 1.24. In most widely used parallel plate capacitor type shown in Fig. 1.24 (a), the…
Parallel Plane Waveguide: Parallel Plane Waveguide - As we know already in connection with transmission lines, that reflections and standing waves are produced if a line is terminated in a short circuit, and that there…
Parallel Operation of Transformer: When the load outgrows the capacity of an existing transformer, it may be economical to install another one in parallel with it rather than replacing it with a single larger unit.…
