Missing-codes tester checks 16-bit ADC in 7 sec
06/10/99 EDN-Design Ideas As the resolution of ADCs increases from 12 to 16 bits and higher, the difficulty in testing the"nomissing-codes"specification grows proportionately. To fully guarantee no missing codes for a 16-bit ADC requires testing all 2 16-1 possible output__ Circuit Design by Mark A Shill, Burr-Brown Corp, Tucson, AZ

Pilot Light Flame Detector with Low-Battery Lockout using a Type R Thermocouple
The LTC1541 combine a micropower amplifier, comparator and bandgap reference in an 8-pin package. The part operates from a single 2.5V to 12.6V or dual ±1.25V to ±6.3V supply with a typical supply current of 5µA. Both the op amp and comparator feature a common mode input voltage range that extends from the negative supply __ Linear Technology/Analog Devices App Note, Apr 8th 2010
PLL implements FPGA-based SDRAM controller
EDN-Design Ideas March 26, 1998 [ NOTE
: File has multiple design, scroll for this one.] As FPGA capabilities increase and time to market decreases, FPGAs gain more acceptance for implementing both data and control paths. Thus, they find wide use as controllers and datapath glue logic for fast-page DRAMs.__ Circuit Design by Eddy Debaere, Barco Graphics, Ghent, Belgium
Precision AC Peak Detector
This unique circuit uses a very inexpensive voltage comparator to form a peak detector. The DC voltage produced tracks the positive peak of the input signal. It works from about ten millivolts to about 10 volts peak to peak. The maximum frequency is about. . . Circuit by Dave Johnson P.E.-February, 2002

Pulse Generator Has 0ns to 10ns Width, 520ps Transitions
It is sometimes desirable to produce extremely short width pulses in response to an input trigger. Such a predictable, programmable short time interval generator has broad use in fast pulse circuitry, particularly in sampling applications. This circuit, built around a quad high speed comparator and a fast gate, has a settable __ Linear Technology/Analog Devices App Note, Mar 25th 2010

Reset Supervisor Waits for Stable Supply
17-Apr-03 EDN-Design Ideas Get more power with a boosted triodeThe power-up cycle of the supply voltage in embedded-system applications is sometimes not a clean event. This fact holds especially true in battery-operated systems, because the insertion of a battery often causes significant ringing or glitching on the supply line(Figure 1). In products with on-off switches, the contact bounce of the switch can cause an unclean power-up__ Circuit Design by Mike Mitchell, Texas Instruments, Dallas, TX

Seven Nanosecond Comparator for Single Supply Operation
AN72 AN72 is an extensive discussion of the causes and cures of problems in very high speed comparator circuits. A separate applications section uses the 7ns LT1394 in V-to-F converters, crystal oscillators, clock skew generators, triggers, sampling configurations and a nanosecond pulse stretcher. Appendices cover related topics. __ Linear Technology/Analog Devices
Synchronized Window Comparator Eliminates Error
05/11/95 EDN-Design Ideas Precision A/D converters need a window comparator. The window comparator in Fig 1a is synchronized to the clock signal. This synchronization eliminates errors that could arise when the input signal crosses the high or low threshold(Fig 1b]unsynchronized to clock.
