High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

Bootstrap circuits are widely used in dc-dc converters to serve as top-side bias voltage supplies. After explaining how bootstrap circuits work, this article will show how versatile they can be. One ...

This video explains the function of diodes and how they are used to control the flow of electrical current in electronic ...

The final part of this series will start with bias servo circuits for automatic set up. The FETs pinch off or threshold voltage can vary widely for the same part number. Depending on the fabrication ...

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 ...

Since 1972, scientists have known there are four basic circuit components, but if you've spent any time in an electrical engineering classroom, you probably only have experience with three: capacitor, ...

If a charged particle beam interacts with structures of different electric conductivity in a microelectronic circuit, this leads to local changes in the electric potential at its surface. In a ...

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 ...

Display Driver Integrated Circuits (DDICs) serve as a critical nexus between image processing units and visual display devices, including LCDs, OLEDs and other emerging panel technologies. These ...

Figure 3: Transient measurements of the open circuit photovoltage evolution. The negative deflection of the transient photovoltage measurements during the 500 ns transient light pulses indicates the ...
