Patent 7738947 was granted and assigned to Chang Gung University on June, 2010 by the United States Patent and Trademark Office.
A biomedical signal instrumentation amplifier is especially suitable for a circuit processing biomedical signals. In a voltage instrumentation amplifier, a biomedical signal level conversion circuit is added to change an input level, reduce signal distortion and noise, and achieve the performance of low voltage, unisource, low noise, high CMRR, and high PSRR.
