Abstract :
CMOS hardware development of a resettable 1 GHz integrator circuit for basis projection or random demodulation in Compressive Sensing is described. To accomplish the projection, a wide bandwidth Integrate Amplify and Dump (IAD) circuit element is combined with several mixers to provide integration over the 1GHz bandwidth. The IAD block design in the IBM8RF process is summarized and test results for the constructed IAD device are presented. Finally, a system design for a multichannel compressive sensing receiver is proposed.
