555 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,__ Circuit Design by J Jayapandian, IGCAR, Tamil Nadu, India

900-Mhz Down Converter Consumes Little Power 06/22/95 EDN-Design Ideas Most 900-MHz down-converter designs are proprietary and, thus, are unavailable to the industry.  The designs that are available are usually discrete or require high voltage, which excludes them from the portable market.  The down converter in Fig 1  is nonproprietary and suits battery-powered applications.  Moreover, you can use the IC__ Circuit Design by Ronald Mancini and Raphael Matarazzo, Harris Semiconductor, Melbourne, FL

Circuit converts pulse width to voltage 10/25/01 EDN-Design Ideas 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__ Circuit Design by James Mahoney, Linear Technology Corp, Milpitas, CA

Circuit Converts Pulse Width to Voltage #3 10/28/99 EDN-Design Ideas The circuit in Figure 1 stems from a radio-controlled modeling application, which requires a voltage proportional to the width of the incoming servo pulses.  The circuit is optimized for a positive-going pulse width of 1 to 2 msec, repeating at intervals of approximately 17 msec.  The output produces a voltage of 0.95V for a 1-msec pulse to 2.25V for a 2-msec pulse.__ Circuit Design by Ron Hegler, Picker International, Cleveland, OH

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__ Circuit Design by Paul Hendricks, Analog Devices Inc, Wilmington, MA
