Abstract

An inverse voltage-to-current conversion circuit for providing a current that is inversely related to an input voltage is disclosed. A first input terminal and a second input terminal receives the input voltage between the first and the second input terminals. A voltage-to-time converter circuit provides a time indicator pulse signal with a pulse width related to inverse magnitude of the input voltage. A time-to-voltage converter circuit provides a voltage indicator signal having a magnitude based on the pulse width of the time indicator pulse signal. A voltage-to-current converter circuit provides a current indicator signal having a magnitude proportional to the voltage indicator signal—the current indicator signal being inversely related to the magnitude of the input voltage.
