LOW-PASS FILTER AND SEMICONDUCTOR DEVICE INCLUDING THE SAME

摘要

A low-pass filter according to an embodiment of the present invention includes a resistance connected between an input terminal and an output terminal, an amplifier, a current source which provides a bias current to the amplifier, a first capacitor connected between the output terminal and the amplifier; and a second capacitor connected between the output terminal and the input terminal of the amplifier. So, the area of the low-pass filter can be reduced without filtering performance.
