1us Light Pulse Discriminator Plus F to V Converter -  This circuit is designed to detect the narrow 1uS pulses produced by the above amplifier circuit. The clean logic type pulses produced by the discriminator are then sent to a frequency to voltage converter. The circuit is designed to process a pulse frequency of 10KHz that is frequency modulated by voice audio signals. The circuit is described in more detail in the receiver circuit section of my Handbook of Optical Through the Air Communications.... [Designed by David A. Johnson]
556 Makes Handy Voltage-to-time Converter -  02/01/01 EDN-Design Ideas  The circuit in Figure 1 is a simple, low-cost voltage-to-time converter using  ubiquitous 555 timer chip. You can use  IC's monostable multivibrator as a voltage-to-time converter by connecting  analog-voltage input to  charging resistor, R, instead of connecting R to VCC. With this modification,....

AN-279: Using the AD650 Voltage-to-Frequency Converter as a Frequency-to-Voltage Converter -  AN-279 Analog Devices Application Notes  (app note added 6/06)

AN795: Voltage-To-Frequency/Frequency-To-Voltage Converter -  Microchip Application Note Published 12-Nov-02  (app note added 2/06)
Circuit converts pulse width to voltage -  25-Oct-01 Issue of EDN  The circuit in Figure 1 converts pulse information to a clean dc voltage by the end of a single incoming pulse. In another technique, an RC filter can convert a PWM signal to an averaged dc voltage, but this method is slow in responding. Converting low-duty-cycle pulse information is slower yet.... [Design Idea by James Mahoney, Linear Technology Corp, Milpitas, CA]
Circuit Converts Pulse Width to Voltage #2 -  10/28/99 EDN-Design Ideas  The circuit is optimized for a positive-going pulse width of1 to2 msec, repeating at intervals of approximately17 msec. The output produces a voltage of0.95V for a1-msec pulse to2.25V for a2-msec pulse....[Design Idea added 4/02] EDN is migrating links.

DDS IC plus frequency-to-voltage converter make low-cost DAC -  5-Feb-04 Issue of EDN  Precision DACs are essential in many consumer, industrial, and military applications, but high-resolution DACs can be costly. Frequency-to-voltage converters have good nonlinearity specifications—typically, 0.002% for the AD650—and are inherently monotonic.  This Design Idea shows how you can use a frequency-to-voltage converter and a DDS (direct-digital-synthesizer] chip for precise.... [Design Idea by Noel McNamara, Analog Devices, Limerick, Ireland]
F/V Converter has High-Accuracy -  05/12/94 EDN-Design Ideas  The high-accuracy frequency-to-voltage converter (FVC] in Fig 1  demonstrates how a synchronous, charge-balance, voltage-to-frequency converter (VFC] can function as a single-supply FVC given proper biasing and level shifting.  This FVC can maintain a monotonic 0.01% linearity error over a 60-dB range of 9.7 kHz to 9.7 MHz; it operates from 12 to 36V power supplies. You can modify the circuit’s prescaler to adapt the circuit to considerably higher frequency ranges.... [Design Idea by Paul Hendricks, Analog Devices Inc, Wilmington, MA]

Monostable makes low-cost F/V converter -  02/18/99 Issue of EDN  The circuit in Figure 1 is a low-cost frequency-to-voltage (F/V]converter. Using a monostable (one-shot]multivibrator, the circuit accepts an open-collector square wave that varies in frequency from 0 to 10 kHz. The one-shot produces....Page includes several designs.  Scroll to find this one.... [Design Idea by Mark Brinegar, Dart Controls Inc, Zionsville, IN]
