Power Supply Cuts Switching Noise In DDR Memory Systems
This design idea describes a unique, low-cost power-supply circuit for a double-data-rate (DDR) memory system. Conventional designs for DDR memories consist of a dual buck converter and a voltage reference. In contrast, this design replaces one buck...

State-Variable Oscillator Suits Ratiometric Capacitive Sensors
Often, it's necessary for a sensor system to compute the ratio of two capacitors. Doing so re-duces the transducer's sensitivity to dielectric errors from such factors as temperature. Furthermore, dual sensors are typically used to double the...

Dual-Gate Inverter Oscillator Saves Power, Boosts LED Brightness
An LED's brightness is directly proportional to the current through it, which creates a challenge for low-voltage and battery-powered applications. But it's possible to increase an LED's brightness without increasing the system's power requirements....
