Abstract
A voltage-to-frequency converter wherein a monostable multivibrator is fed by an integrator which periodically activates a switchable current source coupled to the input of the integrator for a finite period of time and at a rate proportional to the level of an input voltage fed to such integrator. The monostable multivibrator includes nonsaturating switching transistors enabling effective operation of the converter over a relatively wide bandwidth. The converter also includes circuitry to temperature compensate the switchable current source enabling such current source to pass a current pulse having substantially the same finite time duration over the range of operating temperatures.
