In this paper the design of a programmable gain amplifier (0 dBdivide15 dB, 3 dB per step) embedded in the analog base-band chain for UWB Receivers in a standard 90 nm CMOS technology is presented. The design has been realized using a proper Matlab procedure. Due to the large bandwidth required in the UWB Receivers, the procedure takes into account the second order effects related with the opamp parasitic...
In this paper the design of the analog baseband chain for UWB receivers in a standard 90 nm 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 60 dB gain). Due to the large UWB signal bandwidth (250 MHz), the design has been carried-out using a MATLAB model taking into account the capacitance parasitics...
