摘要: A differential amplifier circuit that exhibits low temperature drift and a wide dynamic range includes having first second input terminals, nodes operatively connected to the respectively, signal pair, sampling capacitors switching circuit. During operational phase, connects, plate of capacitor connects plates reference voltage. respective ones nodes. In accordance with another embodiment invention, sensor correction for producing corrected output previously described bridge produces as an pair portion voltage is used form connection correct signal.
