Abstract [en]

In this paper we discuss possible variants of A/D conversion in multi-standard and pure software-defined radio (SDR) receiver architectures. The requirements for the ADC dynamic range and linearity are formulated for the contemporary personal and data-communication RF standards. Two implementation examples of a ADC in 90 nm and 65 nm CMOS are presented. These are a multi-bit first-order ADC aimed at baseband conversion and a one-bit second-order aimed at direct RF conversion, respectively. With limited channel filtering the performance achieved for the baseband ADC is shown to be sufficient. However, for the direct RF ADC the dynamic range and linearity requirements cannot be fully satisfied. The presented work can be considered a step ahead toward a successful implementation of the true SDR in the future.
