摘要：
In a circuit including a differential amplifier, a switching device is coupled to the input terminals of the differential amplifier for periodically applying signals thereto. A second switching device is coupled to the output terminals of the differential amplifier and is synchronized with the switching device coupled to the input terminal. By providing an output signal that is constructed from signals amplified in an inverted and non-inverted mode of the differential amplifier, sources of noise and drift-related errors can be minimized.
