Designers of power supplies and battery chargers are faced with many requirements, driven by the need to minimize manufacturing cost while maintaining standards of product safety. A key component in ...

My caller last week admitted that analog circuit design was a new field of study for him. He had inherited an older design to maintain and perhaps improve. As we reviewed the total system it became ...

In the “Say It with Me” series, we’ll take a commonly used concept out of electronics and explain it the best we can. If there’s something that’s been bugging you, or a certain term or concept that ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

A subject rarely found in circuit design textbooks is the matter of nonlinear junction capacitance, especially reverse-bias junction capacitance, also called depletion capacitance. When it is ...

Trying to get a circuit to sense its own current consumption can be a little tricky. That said, there are plenty of specialist three and four terminal chips that will sense across a resistor in the ...

In this article, we highlight one of the most important architectural traits of new continuous-time sigma-delta (CTSD) precision ADCs: the easy to drive resistive input and reference. The key to ...
