Software defined radios are developed with the aim to demodulate any standard. However, constraints make this practically unfeasible. A sampled analog signal processor was developed performing a fast Fourier transform using voltage samples. The idea is to process any RF signal 0 to 5 GHz using the fast Fourier transform to obtain frequency shifting and filtering, presenting a new approach to bring software radio closer to reality. A second version of the analog signal processor using 65 nm CMOS technology from STMicroelectronics is presented and measured
