op-amps & analog electronics, Analog to Digital Converters (ADC) and Digital to Analog Converters (DAC), Instrumentation Amplifiers, Multiplexer etc are used extensively in signal conditioning circuits.

Micro and Nano sclales in ASIC is mainly related to the packing density of transitors on a chip. How small/thin substrate you use in constructing a CMOS on chip defines these scale.

For signal conditioning of process parameters like Temperature, Flow, Level etc, should we use CMOS: Mixed-Signal Circuit & analog integrated circuits ??

 

As an Electrical Engineer at AgilityEMS I have experience of this.

Yes, CMOS mixed-signal circuits and analog integrated circuits are commonly used for signal conditioning of process parameters such as temperature, flow, and level. CMOS (Complementary Metal-Oxide-Semiconductor) technology is widely used in integrated circuits due to its low power consumption, high packing density, and compatibility with digital logic circuits.

Analog integrated circuits, including operational amplifiers (op-amps), instrumentation amplifiers, multiplexers, and Analog-to-Digital Converters (ADCs) and Digital-to-Analog Converters (DACs), play a crucial role in signal conditioning circuits. These circuits are designed to accurately measure and process analog signals from various sensors and transducers, converting them into digital signals for further processing or control.

The use of CMOS technology in mixed-signal circuits allows for the integration of both analog and digital circuitry on a single chip. This integration offers advantages such as reduced component count, improved noise immunity, and enhanced performance. CMOS technology also enables the implementation of advanced signal processing techniques and allows for miniaturization, making it suitable for applications where space is limited, such as in micro and nano-scale ASICs (Application-Specific Integrated Circuits).

In summary, CMOS mixed-signal and analog integrated circuits are well-suited for signal conditioning of process parameters due to their low power consumption, high integration density, and compatibility with both analog and digital circuits.
