# Analog divider and multiplier

This post tells about analog divider and multiplier and covers an introduction to voltage divider and multiplier. The voltage divider and multiplier are considered as one of the most essential circuits in electronics.

A voltage divider as its name seems that divides the voltage into a smaller voltage at its output from its input. To say more clearly, a voltage divider is such an electronic circuit that turns a large voltage at its input into a smaller voltage at its output. It’s a passive linear circuit known as a potential divider that generates an output voltage as a fraction of its input voltage.

It creates an output voltage of a fraction of the input using two series resistors and an input voltage.

For example, if you need to get a $6V$ circuit but have a $12V$ output then you must need such a circuit that can alter them.

It’s a simple circuit that works like a transformer but it works based upon a very different principle for its operating.

Voltage divider circuit is a circuit that turns the single voltage value into multiple output values. There are two types of voltage circuits and are passive in nature and the other is linear behaviour. Passive in nature circuit has no active elements and the Linear behaviour circuit’s output is linearly proportional to its input. The voltage divider is explained by the following formula ${V}_{out}={V}_{in}\frac{{R}_{2}}{{R}_{1}+{R}_{2}}$.

Further talking about analog divider and multiplier, there are mainly four types of voltage multipliers. There are the following:

• half-wave voltage doubler
• full-wave voltage doubler
• voltage tripler

If you need a higher-value DC output from a lower-value AC input, then you must use a voltage multiplier.  That means a voltage multiplier is such a specialised electronic rectifier circuit that turns the lower voltage of AC electrical power into a higher DC voltage.

It delivers the DC output voltage whose prevalence or value is two, three, or more times broader than the prevalence or value of the AC input voltage. A voltage multiplier performs its working process by operating a network of capacitors and diodes.

Here on the below types of multiplier are depicted.
