Microelectromechanical systems (MEMS) has several names, including micro-electro-mechanical systems, and micromechatronic systems. In Japan, MEMS is called micromachines, while in Europe, it’s referred to as microsystem technology (MST). Whatever name that’s used, MEMS devices are made using components measuring from 1 to 100 μm (0.001 to 0.1 mm), with MEMS devices ranging from 20 μm […]

How does a precision rectifier work?
A precision rectifier, sometimes called a super diode, is an op amp circuit designed to behave like an ideal diode and is used in high-precision signal processing applications. It’s not a synchronous rectifier. The op-amp-based precision rectifier should not be confused with power MOSFET-based synchronous rectification. Because there is no diode voltage drop between the […]
What is PSRR and why is it important in op amps and LDOs?
The power supply rejection ratio (PSRR) describes the ability of a circuit to suppress any power supply variations from passing to its output signal and is typically measured in dB. It’s most often used with operational amplifiers (op amps), dc/dc converters, linear regulators, and low drop out regulators (LDOs). For op amps, the PSRR describes […]
Thick-film resistors feature high temperature stability
Commercial and industrial power electronics increasingly demand robust power supplies with high stability and low thermal resistance. For these requirements, standard chip resistors may not be the best solution. Wide terminal chip resistors, such as Stackpole’s RMCW, provide terminations on the long sides of the chip to provide better current handling and thermal resistance. The […]
