Real-Time Digital Down-Conversion with Equalization

Quality digital down conversion (DDC) is challenging with high-speed time-interleaved analog-to-digital converters (TIADC) due to frequency response mismatches of sub-ADC slices, which cause spurious components. This paper describes a novel method for real-time DDC with slice mismatch equalization.

New Aperture Tuning E-Guide: A Deeper Dive

Aperture tuning is essential in enabling smartphones to operate efficiently over increasing RF frequency bands and support transitions to 5G, but implementation requires in-depth knowledge.
