Monochrome TV Transmitter - Block Diagram and its Workings: The term monochrome stands for black and white. Thus a monochrome TV system does not process variations of colour in a…
Sweep Frequency Generator - Block Diagram and its Workings: A Sweep Frequency Generator is a special type of signal generator which generates a sinusoidal output whose frequency is automatically varied or…
Peak to Peak Detector - Working Principle and Applications: A half-wave rectifier with a capacitor-input filter provides a dc output voltage roughly equal to the peak of the input signal.…
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…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
LM340 Series Voltage Regulator: This LM340 Series Voltage Regulator is typical of the three-terminal voltage regulators. The block diagram is shown in Fig. 43.27. The built-in reference voltage Vref drives…
Fixed Positive Voltage Regulators: The series 7800 regulators provide eight voltage options, rangÂing from 5 to 24 V, as indicated in Table 43.2. These ICs are designed as fixed voltage…
IC Voltage Regulators: IC voltage regulators are versatile and relatively inexpensive and are available with features such as a programmable output, current-voltage boosting, internal short-circuit current limiting, thermal shutdown, and…
