Abstract
A voltage-frequency converter having an integrator of which the inverted input terminal is supplied a voltage to be converted while its non-inverted input terminal is supplied said voltage through a first switch means and a voltage comparator of which the inverted input terminal is supplied an output voltage of said integrator while its non-inverted input terminal is continuously supplied with a constant voltage and selectively supplied with said voltage to be converted through a second switch means, wherein an output of said voltage comparator is made to control said first and second switch means, whereby said voltage to be converted is converted into a signal having a frequency proportional to said voltage to be converted.
Claims3
A voltage-to-frequency converter comprising
- an integrator having an inverting input terminal and a non-inverting input terminal,
- an input signal terminal,
- circuit means connecting said input signal terminal to said inverting input terminal,
- first switch means connecting said input signal terminal to said non-inverting input terminal,
- a signal comparator having an inverting input terminal and a non-inverting input terminal,
- circuit means connecting an output of said integrator to said inverting input of said comparator,
- reference signal means connected to said non-inverting input of said comparator,
- second switch means connecting said input signal terminal to said non-inverting input of said comparator and
- means connecting an output of said comparator to said first and second switch means to concurrently operate said first and second switch means.
