Performs High-Speed Voltage-To-Current, Current-To-Current Conversion - 07/25/02 EDN Design Idea The circuit in Figure 1performs active voltage-to-current
conversion or acts as a variable-gain current mirror with high precision and bandwidth. A typical application
is testing high-speed ICs or other devices that have inputs des. . . [by Ali Mehmed, Nokia UK Ltd, Southwood,

Simple VCO, 300 to 500 Mhz - My Radio amateur callsign is OZ2CPU. I like to use Atmel AVR Atmega PIC16 PIC16F876
PIC16F84. Most electronics easy made for the novice and something is for the more experienced. . . . [oz2cpu

Charge Pump Variation - 04/09/98 EDN Design Idea
(several circuits included, scroll the find this one) A diode-capacitor charge pump is the starting point for
many voltage-to-frequency-converter (VFC] designs. The circuit in Figure 1 uses a variation on that classic
theme to achi. . . [by Stephen Woodward, University of North Carolina, Chapel Hill, NC]
Universal Watchdog Fully Controls µ Preset - 05/25/95 EDN Design Idea Many µPs contain internal watchdog timers, and you may wonder
why you need another stand-alone circuit. Unfortunately, more highly integrated functions have preset
parameters that you may want to change. Also, internal watchdogs . . . [by Terje Kvinge, Nera AS, Kokstad,
