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,.... [Design Idea by J Jayapandian, IGCAR,

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,

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
