  • Time-to-voltage converter
    Patent number: 4504155
    Abstract: A constant current source is provided to charge a reference capacitor. The current is switched to the capacitor by a first high-speed analog switch when a first event occurs and the current is turned off by a second high-speed analog switch when a second event occurs. The voltage produced by the charge on the capacitor is proportional to the time between events. A sample and hold circuit maintains the maximum voltage on the capacitor when the events are periodic.
