Abstract
A multi-input voltage-to-frequency conversion circuit, includes: a multi-input operational amplifier amplifying one of multiple voltage signals in response to multiple control signals to generate an amplified voltage; a voltage-to-current converter converting the amplified voltage into a sensed current, and generating an oscillation current based on the sensed current and on an offset voltage that is associated with a predetermined frequency range corresponding to the one of the voltage signals; and a current-controlled oscillator generating, based on the oscillation current, a periodic pulse signal that has a frequency linearly proportional to the magnitude of the one of the voltage signals.
