Anadigics wins patent for DC-DC converter
In amplifiers using depletion-mode devices such as FETs, there is a need for a bias voltage to turn the devices OFF (non-conducting) from a normally ON (conducting) state. If a depletion-mode device requires a negative bias supply, but the main circuit power supply is positive, then the negative bias potential must in some manner be generated from the positive potential. Anadigics patented invention generates a plurality of output DC voltage levels with the opposite polarity of the DC control voltage. Additionally, it effectively converts the DC control voltage to an output voltage functioning as a DC-DC converter. The device may also be used as a balanced voltage source, which will only have spurious signals at even harmonics of the AC frequency signal. The device is suitable for use in microwave DC-DC converter circuits and as an adjustable low-spurious signal DC-DC converter that can be fabricated as a monolithic integrated circuit.
"This new patent demonstrates that Anadigics has assembled a world class research and development team that is committed to constantly pushing the boundaries of technology and developing cutting edge solutions for our customers, adds Charles Huang, Executive VP and CTO.
