OTA as Programmable Resistor, Grounded Resistor and Floating Resistor: OTA as a Programmable Resistor: We may employ Ic OTA as a programmable resistor whose resistance is controlled by controlling current Ic. We can define resistance,…
OTA Adder (Summer) and OTA Lossy Integrator: OTA Adder (Summer) : OTA adder is shown in Fig. 41.9 for which the output voltage is given as where G = 1/R. This circuit is versatile because…
Oscilloscope Operating Precautions: In addition to the general safety precautions, the following specific precautions should be observed when operating any type of oscilloscope. Most of the Oscilloscope Operating Precautions also apply to recorders. Always study…
Oscilloscope as a Bridge Null Detector: As a null detector for an ac bridge, the oscilloscope, unlike a meter used for the purpose, gives separate indications for reactive and resistive balances of the bridge. Figure…
Oscillator Amplitude Stabilization Circuit: Output Amplitude - For all of the Oscillator Amplitude Stabilization Circuit discussed, the output voltage amplitude is determined by the amplifier maximum output swing. The output waveform may also be distorted…
Optoelectronics Devices Interview Questions and Answers: 1.What are photonic devices? Ans. Photonic devices are those in which the basic particle of light (the photone) plays an important role. Photodetectors, solar cells and LASERS etc, are photonic…
Optocoupler Circuit Operation: An Optocoupler Circuit Operation (optoelectronic coupler) is essentially a photo-transistor and an LED combined in one package. Figure 20-35(a) and (b) shows the typical circuit and terminal arrangement for one such device…
Optimum Generation Scheduling: Optimum Generation Scheduling - From the unit commitment table of a given plant, the fuel cost curve of the plant can be determined in the form of a polynomial of suitable degree…
Optimal Unit Commitment (UC): As is evident, it is not economical to run all the units available all the time. To determine the units of a plant that should operate for a particular load is…
Optimal Two Area Load Frequency Control: Modern control theory is applied in this section to design an Optimal Two Area Load Frequency Control for a two-area system. In accordance with modem control terminology ΔPc1 and…
