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 6<sup>th</sup> &#x2014;order 240MHz Bessel lowpass transfer function. The cut-off frequency is about constant… (More)
