This paper proposes a novel software defined radio (SDR) receiver design using non-uniform sampling (NUS) technique implemented by original design of a pseudorandom signal sampler (PSS) circuit for controlling data conversion to relax multistandard receiver circuit constraints. The proposed and designed NUS-based SDR receiver allows spectral alias suppression at integer multiples of sampling frequency offering the advantages of relaxing anti-aliasing filter (AAF), reducing the analog-to-digital converter (ADC) dynamic power consumption and the automatic gain control (AGC) range as well. The PSS circuit, generating pseudorandom clock signal, with enough time-quantization accuracy, was designed. The PSS is implemented in 65-nm digital CMOS technology and occupies 470(@mm)^2. It features up to 200MHz ''mean clock'' for 3.2GHz main clock while drawing 242@mA for 1.2V supply. Mixed experimental/simulation tests, of designed NUS-based SDR receiver, revealed a confirmation of alias-free performances and the achievement of a 72dB (12-bit ADC) dynamic range after signal reconstruction. |
