A 240MHz programmable gain amplifier & filter for ultra low power low-rate UWB receivers
A 90nm-CMOS power-optimized Programmable Gain Amplifier (PGA) for Ultra Low power Low Rate-Ultra Wide Band (LR-UWB) receivers is illustrated. The PGA features a 0-40dB programmable gain range with a 5dB gain-step. In addition it implements a 6th —order 240MHz Bessel lowpass transfer function. The cut-off frequency is about constant, independently on the different gain settings. At 40dB gain, the input 1dBcp is −44.8dBm, and the NF is 14.3dB. The current consumption (1.9mA at 0dB-gain up to 2.9mA at 40dB-gain) is optimized by including the opamp performance in the cell transfer function, and accordingly to the selected gain level.
