Introduction to Darlington Transistor A Darlington transistor or simply Darlington pair is mainly used to offer a very high current gain even with low base current. Darlington configuration was invented by Sidney Darlington in the year of 1953. In today’s market, wide variety of Darlington transistors are available that are varied by polarity, collector current, power dissipation, package type, maximum CE voltage and so on. These transistors are found in different types of applications such as power regulators, motor controllers, audio amplifiers, etc....

The oscillatory waveform depends on the nonlinear characteristics of the circuit rather than on a frequency selective element. Therefore, these are easy to fabricate as monolithic integrated circuits. Relaxation Oscillator Relaxation oscillators are non-sinusoidal oscillators which generate triangular, square and pulse waveforms using a circuit building block known as multivibrators. When the loop gain is greater than unity and the feedback is positive then the output produced is nearly similar to the sine wave which last for most of the periodic time....

Car parking management in organisations and malls often consists of many tasks like issuing tokens, noting the check-in and check-out time, calculating fare and finally collecting the amount.
