In this paper the design of the analog baseband chain for UWB Receivers in a standard 90nm CMOS technology is presented. The baseband chain is composed by the 5th order Elliptic analog low-pass filter and a Programmable Gain Amplifier (with up to 60dB gain). Due to the large UWB signal bandwidth (250MHz), the design has been carried-out using a MATLAB model taking into account the capacitance parasitics effect and the opamp finite bandwidth impact on the filter transfer function. From a single 1.2V supply voltage, the total power consumption is 13mA per channel, the in-band and out-of-band IIP3 is 20dBm and the maximum IRN for G>15dB is 9nV/√Hz. ©2008 IEEE.

Abstract
In this paper the design of the analog baseband chain for UWB Receivers in a standard 90nm CMOS technology is presented. The baseband chain is composed by the 5th order Elliptic analog low-pass filter and a Programmable Gain Amplifier (with up to 60dB gain). Due to the large UWB signal bandwidth (250MHz), the design has been carried-out using a MATLAB model taking into account the capacitance parasitics effect and the opamp finite bandwidth impact on the filter transfer function. From a single 1.2V supply voltage, the total power consumption is 13mA per channel, the in-band and out-of-band IIP3 is 20dBm and the maximum IRN for G>15dB is 9nV/√Hz. ©2008 IEEE.
