Filter cutoff tracks ADC conversion rate 11/20/97 EDN-Design Ideas The circuit in Figure 1 matches an antialiasing filter's cutoff frequency to an ADC's changing conversion rate.  Two main design requirements are high efficiency and the ability to convert signals with varying bandwidths.  To help conserve power, the circuit uses a low-power switched-capacitor filter and an ADC whose power consumption decreases as its conversion rate decreases__ Circuit Design by Kevin R Hoskins, Linear Technology Corp, Milpitas, CA

Find hex-code values for microcontroller’s ADC voltages 12-Apr-07 EDN-Design Ideas Ease 8-bit microcontroller programming with a simple formula to calculate hex values of ADC output__ Circuit Design by Harry Gibbens Jr, Deafworks, Provo, UT

Flash ADC takes the uncertainty out of high-speed data recover 09/01/98 EDN-Design Ideas Flash ADC takes the uncertainty out of high-speed data recoveryTraditional methods of recovering data and clock information from noisy baseband signals fail at data rates higher than 30 Mbps.  Using the same flash ADC to sample both the input data and its phase eliminates timing errors and makes it possible to recover data at 500 Mbps.__ Circuit Design by Tom Napier, Consultant

Frequency Comparer Produces Binary Result 09/29/94 EDN-Design Ideas Instead of resorting to full-blown frequency counters, the simple circuit in Fig 1 uses four ICs to rapidly compare the frequency of two pulse trains.  The circuit produces a binary 0 if f1 is greater than f2 and a binary 1 if f1 is less than f2.  The circuit exploits the fact that inevitably two consecutive leading edges of the higher frequency pulse train will follow each__ Circuit Design by Jay Kirschenbaum, Columbia University, New York, NY
