ED_ED UPDATE: POWER AND ANALOG_ Penton Media October 26, 2009 If you want to view this on the web go to: http://enews.penton.com/enews/electronicdesign/v/929 POWER DESIGN --Energy Storage Industry Needs Novel Circuits And Semiconductors By Bobby Maher, Full Power Inc. Electric double-layer capacitors (EDLCs), better known as ultracapacitors or supercapacitors, are now a primary energy storage option for design engineers. During the past 10 years, we have seen the emergence of this technology, especially with the move toward "green" and more energy-efficient options. These devices have an advantage over batteries, particularly in applications requiring long life or operation in low temperatures.

But conventional half-wave, full-wave, or bridge rectifiers employing diodes can't be used with low-amplitude signals. The circuit described below is a mixed-mode precision rectifier that can handle both low-amplitude voltage and current signals.
