mixedsignalkredsløb

mixedsignalkredsløb, also known as mixed-signal circuits, are electronic circuits that integrate both analog and digital components on a single integrated circuit (IC). Analog signals are continuous and vary smoothly over time, representing physical quantities like temperature or sound. Digital signals, on the other hand, are discrete and represent information as binary values, typically 0s and 1s. Mixed-signal circuits are essential for bridging the gap between the real, analog world and the digital world of processing and computation.

The primary function of a mixed-signal circuit is to convert signals from one domain to the other. For example, an analog-to-digital converter (ADC) takes a continuous analog input and converts it into a series of discrete digital values. Conversely, a digital-to-analog converter (DAC) performs the opposite function, transforming digital data back into an analog signal. These conversion processes are fundamental to many modern electronic devices.

Applications of mixed-signal circuits are widespread. They are found in virtually every electronic system that interacts with the physical environment. This includes consumer electronics like smartphones, televisions, and audio equipment, as well as industrial control systems, automotive electronics, medical devices, and telecommunications infrastructure. Without mixed-signal circuits, it would be impossible for digital processors to interpret real-world sensory data or to generate analog outputs for actuators or displays. The design and fabrication of mixed-signal ICs present unique challenges, requiring expertise in both analog and digital circuit design techniques.
