ABSTRACT:
A bioelectric impedance measuring circuit for applying a current to an organism and measuring a bioelectric impedance of the organism is disclosed that includes a pseudo-sine wave generating circuit for generating a pseudo-sine wave based on an input square wave, a voltage/current converting circuit for outputting current to the organism in correspondence with the pseudo-sine wave generated by the pseudo-sine wave generating circuit, and a processing circuit for generating the square wave and supplying the square wave to the pseudo-sine wave generating circuit and measuring the bioelectric impedance based on a voltage output from the voltage/current converting circuit. The pseudo-sine wave generating circuit is included in a semiconductor integrated circuit.
