Abstract

A small sensor circuit with reducible electric power consumption is formed by connecting inverting amplifiers comprised of CMOS inverters connected in an odd number of stages, in series to guarantee the linearity of the relationship between inputs and outputs, and connecting an impedance as a sensor between the inputs and outputs, or to an input.
