    摘要: An integrated circuit device includes a differential amplifier having first and second input terminals and at least one output terminal. The first input terminal is configured to receive a reference voltage and the second input terminal is configured to receive a time-varying input signal. A normally-on CMOS transmission gate is also provided. The CMOS transmission gate has an input terminal configured to receive a reference voltage and an output terminal electrically coupled to the first input terminal of the differential amplifier. This CMOS transmission gate operates to reduce fluctuations in the reference voltage caused by kick back noise by adding parasitic capacitance to the first input terminal of the differential amplifier.
