This book describes novel circuit and system solutions for the design of analog electronic interfaces for resistive, capacitive and temperature sensors, also showing a wide variation range, with the intent to give a complete overview of the first analog front-ends. After a description of the main kinds of sensors and their definitions, the book presents novel electronic circuits, most of which do not require any initial calibration, also designed with analog microelectronic techniques, at transistor level in a standard CMOS integrated technology.
These solutions utilize both AC and DC excitation voltages for the employed sensor and are developed both in Voltage-Mode approach (which considers the use of Operational Amplifiers or Operational Transconductance Amplifiers as the main active blocks) and in Current-Mode approach (using the Second Generation Current Conveyor as the main, active device), as well as with Low Voltage Low Power characteristics when designed for portable applications and instrumentations.
