Equivalent Transistors - (circuit / schematic design added 6/06)
|
FET audio mixer (Aaron Cake) - This simple circuit mixes two or more
channels into one channel (eg. stereo into mono)....(circuit / schematic design added
7/02) |
FET biasing targets battery-powered PWM applications - 21-Nov-05 Issue of
EDN Reference provides constant bias voltage regardless of supply-voltage
variations.... [Design Idea by Steve Franks, Franks Development LLC, Tucson, AZ;
Edited by Brad Thompson and Fran Granville] |

FET Input High Speed Light Detector - This circuit is yet another design
that converts current from a PIN photo diode to a voltage. It has a bandwidth that
extends beyond 50MHz. …. [Designed by David A. Johnson] |
FET Preamp Cable - .... |
|
Finger Touch Activated Switch - It does not get any easier if you want a
solid-state switch that is activated by the touch of a finger. Two small metal pins
route voltage through the finger skin to a MOSFET switch. The circuit is great for
situations where a membrane type mechanical switch is not desired. …. [Designed by
David A. Johnson] |
FM Transmitter - A compact 2 transistor transmitter for use at VHF
frequencies…. [Andy Collison] |
Full Featured Transistor Tester - Just the thing to check the transistors
for any project .... |
Fuzz-box - All-FET design. Valve-like distortion behavior (added 3/05)
|
Gate-drive method extends supply's input range - 26-Jun-03 Issue of EDN
Industrial and telecom applications often require a nonisolated, low-voltage supply
from a high-voltage input. IC manufacturers have responded to that need with the
application of high-voltage processes and offer control ICs that work to 50V and
higher. That voltage is sometimes insufficient, and you need further design techniques
to extend the input voltage.... [Design Idea by John Betten and Robert Kollman, Texas
Instruments, Dallas, TX] |
