Abstract
A CMOS amplifier of a filter for an ultra wideband application and a method of the same are provided. In the CMOS amplifier, an active load circuit adds a Zero location and increases a gain by MOSFETs, feeding back operation, and has a property of a high gain and a wide bandwidth. When the CMOS amplifier is applied to a biquad LPF, a high voltage linearity over about 200 mV peak-to-peak and an suitable ultra wideband property over about 320 MHz of an cutoff frequency may be achieved.
