Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Interfacing laser driver circuits with commercially available laser diodes at high data rates can be a complicated and frustrating task. This application note is intended to briefly address this topic ...

A previously-published Design Idea outlined a polarity protection circuit that provides the correct connection of the battery to a load regardless of the battery’s orientation in its holder. The ...

In some power-supply applications, the pulse-width-modulator (PWM) controller is powered up from an auxiliary winding tapped off the power stages transformer (Fig. 1). This technique reduces power ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...

A diode is a tiny component that controls the flow of electricity by allowing current to pass in only one direction. This video explains how diodes work, what makes them unique, and why they’re used ...

In the realm of modern electronics, semiconductor diodes have emerged as fundamental components with diverse applications. One of their pivotal roles lies in the fields of rectification and voltage ...

Many embedded systems require a stable, low-noise DC reference. This reference can be a stable current or voltage source. These references are used in many ways. Some typical uses are listed as ...

A semiconductor diode is an electronic component that allows current to flow in only one direction, acting like a one-way valve for electricity. It is commonly used for voltage regulation, converting ...
