Addressing Modes of 80186: The 80186 provides eight different types of addressing modes to specify operands. The operand (data) is used in the instruction to specify the addressing modes. The addressing mode byte is always…
Darlington Amplifier - Circuit Diagram, Characteristics, Merits and Applications: Darlington amplifier with voltage divider bias is shown in Fig. 19.50. In this circuit the output of one amplifier is coupled into the input of the…
Homogeneous Linear Differential Equations: Consider an nth order homogeneous linear differential equations with constant coefficients, where a0, a1 ... an are real constants. Now we shall find the solution of Eq. 11.11 of the form…
Operations of Traction Power Controller (TPC): It is provided to have a comprehensive picture of supply conditions and arrangement to operate switchgear with minimum delay so that continuity of electric supply to the track, which…
Crystal Equivalent Circuit: Crystal Equivalent Circuit - The output frequency of oscillator circuits is normally not as stable as required for a great many applications. The component values all have tolerances, so that the actual…
Multivibrator definition and Types (Astable, Monostable and Bistable): A multivibrator is basically a two stage R-C coupled amplifier with positive feedback from the output of one amplifier to the input of the other, as illustrated…
Constant Current Limiting Circuit: A block of series regulation using simple Constant Current Limiting Circuit is shown in the Fig. 2.119. It is also called short circuit protection circuit as it provides protection against short…
Ion Implantation Process in IC Fabrication: As we know, the conductivity of the semiconductor increases when small impurity is added to it. The process of adding impurity is called doping while the impurity to be…
Automatic Frequency Control Block Diagram: Automatic frequency control: As previously we see, the heart of an AFC circuit is a frequency-sensitive device, such as the phase discriminator, which produces a dc voltage whose amplitude and…
What is Diode Resistance? What is Diode Resistance? - As already discussed, a forward-biased diode conducts easily whereas a reverse-biased diode restrains the flow of current, so a diode has a low forward resistance as…
