Microsystems, which are key components in portable, miniature and high-volume sensing applications, increasingly require low-power/lowvoltage (LPLV) electronic circuits. The impact of sensing concepts and specifications on power consumption in microsystems is investigated. Examples of LPLV interface circuits for piezoresistive and capacitive sensors are presented.
