Abstract: A heat sensitive flow meter comprising a power source for changing an offset voltage &Dgr;E at the time of application of a power voltage. The power source is connected to the non-inversion input terminal of an operation amplifier for amplifying a potential difference between a first heat sensitive element for measuring the temperature of a fluid and a second heat sensitive element which is cooled by the fluid. The heat sensitive flow meter can suppress an output error right after the application of a power voltage and shorten a target signal reach time.

Abstract: A signal processing circuit can obtain a ratiometric output with high precision and high responsiveness in a relatively easy and simple way. A pulse generation circuit generates a pulse signal corresponding to an input signal. An integration part generates an integrated voltage having a time slope proportional to an input voltage with a duration specified by the pulse signal being set as an integration period. A hold part holds and outputs a difference voltage between a start voltage and an end voltage of the integrated voltage in the integration period. The integration period is specified at the timing of the pulse signal output from the pulse output circuit, and a ratiometric output is generated by sample holding the integral signal.
