The electrification of vehicles has spurred an increased demand in accurate current measurement in new electronic drive systems, such as traction inverters, DC-DC controllers, battery managements ...

A high-side current-sense amplifier must be protected against reversed battery connections or inductive kickbacks or other negative-voltage transient. This Idea for Design describes a circuit using ...

Sometimes I wish FETs had become practical before bipolar transistors. A FET is a lot more like a tube and amplifies voltages. Bipolar transistors amplify current and that makes them a bit harder to ...

Spice model makes it easy to design with PWM amplifiersHigh-efficiency PWM amplifiers are displacing linear designs in many applications. You can design a constant-current or a constant-voltage PWM ...

Using a resistor and voltage amplifier across it for current sensing presents a conundrum. On one hand, it appears to be near-trivial application of Ohm’s Law via I = V/R. It certainly looks easy: A ...

Current‐mode amplifiers have emerged as a highly efficient alternative to traditional voltage‐mode systems, particularly in high frequency and low power electronic applications. Their ability to ...

Feedback refers to a core concept in circuit design and control theory, used to stabilize amplifiers and control system ...

High performance with low power consumption: this requirement is coming to bear in more and more applications, especially when it comes to mobile, battery-operated devices. Particularly in the times ...

Learn how power amplifiers work, the common types, and what to lookout for when shopping for amps. You have to find out if the amplifier is a Class A/B analog amp or a Class D digital amplifier before ...
