Performance-Enhanced Data Acquisition
Overview
SP Devices provides signal processing IP for digital performance enhancement of analog-to-digital conversion and input signal paths. The IP products are available for implementation in application specific integrated circuits (ASICs) or for integration on field-programmable gate array (FPGA) platforms. Our portfolio of products enables our customers to build systems with state-of-the-art analog-to-digital performance that enables advances in areas such as broadband communcation transceivers, instrumentation, high-speed data acquisition, Radar, and signals intelligence. We also incorporate our IP in our range of high-speed digitizers.
DBS - Digital Baseline Stabilizer for Time-Domain Pulse Applications
Baseline (DC level) drift caused by temperature fluctuations and other factors can result in false readings and/or performance degradation in time-domain pulse applications. Furthermore pattern noise from time-interleaved ADCs makes the situation even worse.
ADX - Time-interleaving Technology for Analog-to-Digital Converters (ADCs)
Time‑interleaving of analog‑to‑digital converters (ADCs) is a way to increase the overall system sample rate by using several ADCs in parallel. The challenge is to handle the mismatch between the individual ADCs, especially at higher frequencies.
ADL - Linearization Technology for Signal Path Performance Enhancement
Digital post‑linearization increases the effective resolution of analog‑to‑digital conversions. The ADL linearization technology developed by SP Devices suppresses performance-limiting non‑linearities of ADCs and the preceding signal path (amplifiers, filters, buffers, etc.).
IQE - I/Q Imbalance Correction Technology
Digital I/Q imbalance correction match the in-phase and quadrature signal paths in radio architectures employing complex demodulators such as direct down-conversion receivers. The distortion due to signal path imbalances is attenuated effectively over a large bandwidth.
