A Current Steering Folding Amplifier
The analog-to-digital converter (ADC) is a key functional building block in most analog/digital VLSI systems. Most applications require high-speed ADC�s with low power consumption. Our technology provides a novel current steering folding amplifier that significantly reduces the power dissipation of a folding A/D converter and also reduces the number of reference current sources.
The current steering folding amplifier has several advantages when compared to conventional amplifier (discussed below). Its highlighting feature is its lower power consumption. This technology can be used in high speed applications such as network router, wireless communication, flat-panel display and hand-held multimedia devices.
Stage of Development
A provisional patent has been filed with the U.S. Patent and Trademark Office and the application is pending. This technology has been demonstrated to work in proof-of-concept experiments. It is available for developmental research support/licensing under either exclusive or non-exclusive terms.
