Abstract
A frequency to voltage converter includes an operational amplifier having its non inverting input terminal connected to a supply line which has a voltage intermediate a pair of supply terminals for the amplifier, a resistor connected in series with first and second diodes between the inverting input terminal and the line a first capacitor through which the input of the converter is connected to a point intermediate the diode and a second capacitor connected between the junction of the first diode and the resistor and one of the supply lines, a feed back resistor connected between the output terminal of the amplifier and the junction of the first diode and the resistor and a third capacitor connected between the output and inverting input terminals of the amplifier.
