  • Measurement System with large dynamic range
    Patent number: 5880827
    Abstract: A measurement circuit having high dynamic range includes high-gain and low-gain amplifiers connected in parallel. A shunt feedback circuit is activated to prevent the high-gain amplifier from saturating when the magnitude of an input signal exceeds its dynamic range. The output of the high-gain amplifier is utilized to measure small input signals and the output of the low-gain amplifier is utilized to measure large input signals.
