This adaptation of a superbal circuit allows for adjustable gain without CMRR degradation.

Compensate the DC voltage drift in the output of a directly-coupled power AB-Class audio amplifier to improve bass response.

This Design Idea provides complete instructions for designing solar day lamps using both passive and active current limiting circuits.

This circuit employs a novel high-efficiency H-bridge driver topology to drive a thermoelectric cooler element without introducing noise into the desi...

Here's a novel approach for improving the accuracy and settling time of PWM-based DACs.

Before people knew about electricity, many natural phenomena appeared as supernatural events caused by angry gods. Fortunately, people today know phys...

The unintended reversal of battery polarity can be anything from an annoyance to a disaster. This circuit connects the battery to its load with the co...

An easy method to control the output of a power supply is to use a current mirror.

This design shows how a piezoelectric transducer's acoustic output can be increased while minimizing the parts count and cost.

Using only generic components, this Design Idea implements an optically-isolated current sense topology compatible with DC sources of either polarity,...
