Abstract :
A report is presented on the hardware implementation of a parallel multi-channel sampler in 0.5 μm CMOS technology. The system consists of eight parallel analogue processing channels, each one capable of modulation by a programmable binary chipping sequence. System operation is demonstrated in both Nyquist and compressive sampling of test signals.
