Time-tag impulses with zero-crossing circuit - 24-Jan-02 Issue of EDN
A "constant-fraction discriminator" usually performs the time-tagging of impulsive
events, which have a peaking time of the signal amplitude. The implementation of this
technique requires a delay in the input signal of approximately the same amount as the
signal's rise time. You can attain this delay by using a coaxial cable of an
appropriate length..... [Design Idea by Elio Rossi, Itesre-CNR, Bologna, Italy] |

Transistor Forms RS232C Digital Thermometer - 05/09/96 EDN-Design
Ideas.....An ordinary transistor can serve as an uncalibrated temperature sensor

than0.5°:C over the -50 to +50°C range, and the only limitation on resolution is the
time devoted to measurement acquisition..... EDN is migrating links. This link is not

Trigger a TTL circuit from ECL levels - 8-Nov-01 Issue of EDN ECL
circuits typically have relatively small logic spans of approximately 800 mV. Because
of the small span, to drive TTL circuits from ECL levels normally entails the use of
level converters, such as the MC10125, or comparators. Such circuits are relatively
power-hungry and expensive. However, they are sometimes simply unnecessary.....

Two chips simplify layout for high-end embedded control - 04/01/99 Issue of
EDN If you are considering using one of the 32- or 64-bit RISC µPs from
Integrated Device Technology (IDT], the company’s new RC32134 and RC64145
system-controller ICs (Picture] can make your job easier. The chips provide
synchronous-DRAM, memory, and I/O control; a PCI interface; and peripherals, including
UARTs, timers, and interrupt controllers. The 32134 for the RC32364 µP provides a
glueless interface to DRAM.....Page includes several designs. Scroll to find

Two DDS ICs implement amplitude shift keying - 25-Dec-03 Issue of EDN
Many communications systems, including RFID systems and cable modems, use AM
(amplitude modulation]. This Design Idea shows how two DDS
(direct-digital-synthesis] devices can implement AM and ASK (amplitude-shift keying]
over a range of frequencies. The AD9834 complete 50-MHz DDS IC (Figure 1] has a
current output, so you can easily sum the outputs of two orof them by connecting them
to a..... [Design Idea by Noel McNamara, Analog Devices, Limerick, Ireland] |

Two Transistors Form Bidirectional Level Translator - 11/07/96 EDN-Design
IdeasThis example illustrates a translation from 5 to 3V, but it can accommodate
almost any other voltage levels, provided the logic-low levels are equal (usually0V].
Translations from 1 to 100V are possible, albeit rather slow. The key to this circuit
is the unusual cross-coupling of the emitters..... [Design Idea by Jim Hagerman, Nokia

Two-Transistors Form Bidirectional Level Translator - You often need to
convert a logic signal from one power supply voltage to another. This conversion
is a relatively simple task, unless the signal happens to be bi-directional. Serial
buses such as Access.bus, I2C, and SBI use bi-directional data lines. Some buses may
require translating logic from one voltage to another; for example.....[Jim Hagerman,
