Tackling mixed signals
Why integrated ASICs and ADCs are the premier solution
T
he continuous processing of signals from the real world is what makes smart sensors a success. It ensures that data is presented in a way that is valuable to control systems, so they can determine the right actions to take and, ultimately, enhance performance. Here, Ross Turnbull, director of business development and product engineering at custom IC design and supply specialist, Swindon Silicon Systems, explains why integrated mixed-signal solutions are crucial to industrial sensing systems.
Signal processing is a critical aspect of electronic systems, ensuring that signals are accurately converted to generate actionable insights. This process involves
signals to meet the needs of the subsequent stages of data processing.
Some signal processing and conditioning focuses on solely analogue or solely digital applications. Analogue signals from capacitive elements, magnetic heads and thermal sensing elements all require a outputs and ensure any erroneous data is avoided.
The same goes for solely digital applications. Memory controllers, calibrators and threshold settings all need to process input signals through algorithms and compare them with reference data to ensure the signals are ready for next steps. The real crux of signal conditioning is in mixed-signal applications.

Mixed-signal processing applications involve converting analogue signals into digital, or vice versa, to gain insights from the real world. One key component used in many of these applications is a high-resolution Analogue-to-Digital Converter (ADC), which plays a crucial role in maintaining signal integrity, transforming analogue signals into digital data with minimal loss. In the automotive sector, signal conditioning enables the precise detection and processing of a wide range of analogue inputs, from engine sensors to tyre pressure monitoring systems (TPMS). This data is then processed in real-time to ensure optimal provide warnings to drivers if certain vehicle
