How to Convert Binary into Decimal?

To convert binary into decimal, each bit of the binary number is first multiplied with 2(n-1) where n is the position of the particular bit when counted from Least Significant Bit (LSB). The result so obtained are then added to get the equivalent decimal number. We will discuss the entire process / method of converting … Read more

How to Convert Decimal Number into Binary?

An easy method of converting a decimal number into binary number is by dividing the decimal number by 2 progressively, until the quotient of zero is obtained. The binary number is obtained by taking the remainder after each division in the reverse order. This method to convert decimal number into binary number is popularly known … Read more

What is Tunnel Diode?

A tunnel diode is a diode that exhibits a negative differential impedance region in its I-V characteristic due to quantum tunneling effects. That is, a -sloped region as shown by red colored region in the figure below. It’s a diode, a kind of semiconductor device usually with two terminals. Unlike a regular pn diode, Tunnel … Read more

How Twisting the Cables Reduce the Interference?

Twisting the cables is done to remove the electromagnetic interference from the wires. When a signal is transmitted through the cable it is in the form of current. This flow of current produces an electromagnetic field of interference around it and can generate noise effects in the surrounding cables. One pair can induce cross-talk in … Read more

Difference between Depletion-mode MOSFET and Enhancement-mode MOSFET

Enhancement Mode MOSFET: For an enhancement MOSFET, the channel does not initially exist. It only comes into existence once a voltage greater than Vth, threshold voltage is applied. For example, in an n-channel MOSFET, the substrate is made of p-type material. Consider the source to be at a reference ground potential of 0 Volts. For … Read more
