Differential driver doubles as versatile RF-switch driver - 6-Jan-05 Issue
of EDN Designed as a high-speed driver for 12-bit ADCs, the AD8137 controls SPDT
GaAs (gallium-arsenide] FET-MMIC (microwave-monolithic-IC] and PIN-diode RF switches
and thus provides a low-cost and versatile alternative to conventional switch drivers.
This circuit achieves typical switching speeds of approximately 7 to 11 nsec,
including the propagation delays of the driver and RF load..... [Design Idea by John
Ardizzoni, Analog Devices, Wilmington, MA] |

Digisound ring modulator - Dual Ring Modulator based on MC1496. The X and Y
inputs are AC coupled and are capable of accepting 10V p-p signals. Comprises two
totally independent ring modulators on the same PCB which produces the sum and
difference with two input signals. Ideal for the production of a whole range of sounds
including bell and gong sounds..... |

Driver Thermally Compensates LED - 09/02/99 EDN-Design Ideas.....Optical
power of popular types of LEDs decreases with temperature. Optical-power measurements
into a typical multimode fiber at 62.5/125 ?m for a GCA 1A194 LED indicate a
temperature coefficient of approximately -0.4%/°C. In bipolar analog drivers for
short- and medium-distance fiber links [Design Idea by Andrzej Wolczko, University of

Driving a Capacitive Load - You've been warned! Do not attempt to drive
large capacitances with your op amp, severe overshoot and ringing may occur. But what
if you're stuck driving a length of coax cable that's unterminated? You could end up
with over 1000 pF that sends the output ringing. What causes this behavior?
Unfortunately.....(spice design added 02/09) |
