Analog Logic
Abstract
The Analog Logic program developed and demonstrated architectures, designs, and development tools for implementing computational functions in analog circuitry to overcome performance limitations inherent in digital designs. This program applied the technologies to signal processing functions typically performed in digital form, which experience design complexity, high power consumption, thermal loads, limits to computational speeds, loss in dynamic range, and susceptibility to manufacturing variances. The Analog Logic program built and demonstrated an analog-only signal processing capability with no local oscillator, down-conversion, or analog-to-digital conversion. The goal was to achieve a 10 times reduction in gate count, a 1024 Point Fast-Fourier Transform (FFT) with 8 bits equivalent dynamic range, and functional performance within 0.5dB of digital performance. Further, the program investigated the system-level impact of Analog Logic on other embedded processing problems as well as the feasibility of creating programmable embedded processing solutions in this technology. This program will transition to both Industry and NSA.
