ABSTRACT:
A frequency to voltage converter is described which utilizes an operational amplifier connected as a damped integrator and having a switched capacitive input and feedback element. If the capacitors are equal in size, the output voltage is a function of the ratio of the switching frequencies of the switched capacitors.
