Adaptive Signal Cancellation (ASC™) Analog-to-Digital Conversion

Adaptive Signal Cancellation, Improving Analog-to-Digital Conversion

Innovation Digital provides patented signal processing solutions for analog-to-digital conversions for extremely wide band and wide dynamic range digitization. An example would be the ability to provide ultra high RF receiver performance in high-power co-site interference environments (e.g., 16 bits at 1.8 GSPS).

The approach uses digital filtering that is adaptively optimized to provide gain and phase matching that provides a high degree of signal cancellation over an extremely wide bandwidth and over time and temperature. A multi-stage, subranging type architecture is used to generate the cancellation signals and successively cancel large signals so that the remaining smaller signals can be amplified and digitized with high-resolution.
