Abstract

The reconfigurable analog signal processor (RASP), one of the first large-scale field-programmable analog arrays (FPAAs), is composed of 56 computational analog blocks (CABs). Each CAB contains various levels of analog computational granularity utilizing over 50,000 programmable analog elements. Bias currents are programmable to within 0.2% from 100 pA to greater than 3 muA. Internal bandwidths are greater than 50 MHz, and the kT/C noise can be adjusted using the drawn capacitances and routing network parasitics. A range of compiled circuits and resulting signal processing systems are presented
